Integration of phenylammoniumiodide (PAI) as a surface coating molecule towards ambient stable MAPbI3 perovskite for solar cell application

In the present work, different hybrid perovskites were synthesized by gradual concentration variation of larger cation of phenylammoniumiodide (PAI) and methylammoniumiodide (MAI) in PbI2 solution with the aim of improving the stability of MAPbI3 film and photovoltaic efficiency. To understand the properties of perovskite like structural, optical, thermal, morphological and chemical state, extensive characterizations such as XRD, UV?visible spectroscopy, FE-SEM, SEM, EDX and XPS were performed. The role of PAI was investigated further with the use of DFT studies. The DFT results confirmed that the PAI was passivated on the surface of MAPbI3 with most stable arrangement. The stable arrangement revealed the formation of ?-? interactions within the phenyl rings, which shielded the MAI crystals and thereby resulted in enhanced stability of the perovskites. Highly protected perovskite consequently yielded high- performance solar cell device with enhanced stability under 60% humidity, high temperature exposure and longer time stability even when directly exposed to normal room temperature. The new investigation of capping techniques with the use of bigger organic molecules, high performance solar cell with low device costs could emerge. This could lead to unprecedented rapid progress on power conversion efficiency (PCE). Thus, more stable organic-inorganic hybrid perovskites could be developed for future applications.

Non-centrosymmetric CuSCN based coordination polymers with substituted pyrazine and pyrimidine ligands

Non-centrosymmetric one- to three-dimensional CuSCN-based coordination polymers with substituted pyrazine or pyrimidine spacer ligands can be prepared by self-assembly in acetonitrile solution at 100C. Both 1?[CuSCN(2NCpyz)2] (1) (2 NCpyz = 2-cyanopyrazine) and 1?[CuSCN(4 HOpym)2] (3) (4 HOpym = 4-hydroxypyrimidine) contain single zigzag CuSCN chains as their central backbone and crystallise in polar space groups (monoclinic Cm and orthorhombic Ama2). In 2?[(CuSCN)2(mu-2Mepyz)] (2) (2Mepyz = 2-methylpyrazine), 1?[(CuSCN)2] staircase double chains are connected by bridging 2 Merpyz ligands to afford a lamellar polymer (triclinic P1). Whereas 2?[CuSCN(5 Brpym)] (4) (5 Brpym = 5-bromopyrimidine) with its honeycomb 2?[CuSCN] layers is chiral (monoclinic P21), both 3D polymers 3?[(CuSCN)2(mu-pym)] (5) and 3?[(CuSCN)3(mu-4 Mepym)] (6) (4 Mepym = 4-methylpyrimidine) contain polar coordination networks (orthorhombic Fdd2 and monoclinic Pc). The CuSCN framework in (5) consists of thiocyanate bridged 1?[CuS] chains, that in 6 of interlocked 2?[CuSCN] and 2?[Cu2S(SCN)] sheets.

Copper and Gold Cyclic (Alkyl)(amino)carbene Complexes with Sub-Microsecond Photoemissions: Structure and Substituent Effects on Redox and Luminescent Properties

Copper and gold halide and pseudo-halide complexes stabilised by methyl-, ethyl- and adamantyl-substituted cyclic (alkyl)(amino)carbene (CAAC) ligands are mostly linear monomers in the solid state, without aurophilic Au???Au interactions. (Et2L)CuCl shows the highest photoluminescence quantum yield (PLQY) in the series, 70 %. The photoemissions of Me2L and Et2L copper halide complexes show S1?S0 fluorescence on the ns time scale, in agreement with theory, as well as a long-lived emission. Monomeric (Me2L)CuNCS is a white emitter, whereas dimeric [(Et2L)Cu(mu-NCS)]2 shows intense yellow emission with a photoluminescence (PL) quantum yield of 49 %. The reaction of (AdL)MCl (M=Cu or Au) with phenols ArOH (Ar=Ph, 2,6-F2C6H3, 2,6-Me2C6H3, 3,5-tBu2C6H3, 2-tBu-5-MeC6H3, 2-pyridyl), thiophenol, or aromatic amines H2NAr?? (Ar?=Ph, 3,5-(CF3)2C6H3, C6F5, 2-py) afforded the corresponding phenolato, thiophenolato and amido complexes. Although the emission wavelengths are only marginally affected by the ring substitution pattern, the PL intensities respond sensitively to the presence of substituents in the ortho or meta positions. In gold aryloxides, PL is controlled by steric factors, with strong luminescence in compounds with Au-O-C-C torsion angles <50. Calculations confirm the dependence of oscillator strength on the torsion angle, as well as the inter-ligand charge transfer nature of the emission. The HOMO/LUMO energy levels were estimated based on first reduction and oxidation potentials.

Homonuclear and heteronuclear complexes of calix[4]-bis-monothiacrown-5 with oligomer and polymer structures

Homo- and heteronuclear complexes (1-7) of calix[4]-bis-monothiacrown-5 (L) with mercury(II), cadmium(II), copper(I), and potassium(I) salts adopting dimer, tetramer, one-dimensional (1D), and two-dimensional (2D) polymer structures with different coordination modes and connectivity patterns were prepared and structurally characterized. Reactions of L with mercury(II) iodide and mercury(II) thiocyanate afforded a dimer complex [Hg4(L)2I8]·CH2Cl2 (1) and a 1D coordination polymer {[Hg2(L)(SCN)4]·CH2Cl2}n (2), respectively, in which the exocyclic dimercury(II) complex units of L are doubly linked by the anions. Reactions of L with cadmium(II) iodide in the absence and the presence of mercury(II) iodide gave isostructural 1D coordination polymers [Cd2(L)I4]n (3) and {[Cd2(L)I4][CdHg(L)I4]}n (4), respectively. In the isostructure of 3 and 4, the ligands are alternately linked by the exocyclic M-I2-M squares via monocadmium(II)-mediated and dicadmium(II)-mediated modes, respectively. Reaction of L with copper(II) thiocyanate in the presence of potassium(I) thiocyanate afforded a discrete complex {[(K2L)4Cu6(SCN)10][K2L]2[Cu(SCN)3]3·2CH2Cl2·CH3CN} (5) consisting of three separated parts: dipotassium(I) tetramer part linked with a oligomer copper(I) thiocyanate backbone, dipotassium(I) monomer part, and trithiocyanato copper(I) complex part. When a mixture of mercury(II) thiocyanate and potassium(I) thiocyanate was used, a grid-type 2D heteronuclear polymer complex [Hg3(K2L)(SCN)8]n (6) in which the 1D mercury(II) thiocyanato backbones cross-linked by endocyclic dipotassium(I) complex units of L was isolated. One pot reaction of L with a mixture of iodide salts of potassium(I), mercury(II), and cadmium(II) gave a binary mixed product of a discrete complex [(K2L)2(Cd3I8)][Cd4I10] (7) and a heteronuclear 2D network (8) which can be manually separated because of the colorless platy and orange-yellow block shapes of the crystals, respectively. In 7, the endocyclic dipotassium(I) complex of L is linked by Cd3I8 clusters. (Chemical Equation Presented).

Development of environmentally friendly antifouling paints using biodegradable polymer and lower toxic substances

The development of new antifouling coatings with respect to the marine environment is actually crucial. The aim of the present work is to concept an erodible paint formulated with biodegradable polyester as binders and which combines two modes of prevention: chemical and physical repelling of biofouling. This system is principally dedicated to disturb durable settlement of microfouling. Each component was chosen according to its specific properties: chlorhexidine is a bisdiguanide antiseptic with antibacterial activity, zinc peroxide is an inorganic precursor of high instable entities which react with seawater to create hydrogen peroxide, Tween 85 is a non ionic surfactant disturbing interactions between colonizing organisms and surface. Obtained results highlighted the interest on mixing such molecules to obtain a promising coating with lower toxicity than traditional systems.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 1111-67-7, you can also check out more blogs aboutRelated Products of 1111-67-7

Novel mixed-metal-alkynyl complexes stabilised by di-imine ligands: Synthesis, characterisation and electrochemistry of [(tBu2bipy)Pt(C?CR)2M(SCN)] (R = C6H4Me, SiMe3; M = Cu, Ag)

Reaction of (4,4?-bis-tert-butyl-2,2?-dipyridyl) platinum bis-alkynyl [(tBu2bipy)Pt(C?CR)2] (R = C6H4Me 1a, SiMe3 1b) with Group 11 metal thiocyanate salts (M = Cu, Ag) affords 1:1 mixed-metal complexes [(tBu2bipy)Pt(C?CR)2M(SCN)] (M = Cu, R = C6H4Me 2a, SiMe3 2b; M = Ag, R = C6H4Me 3a, SiMe3 3b). X-ray analyses of the complexes 2a and 3b show that the group 11 metal is bonded in an eta2 fashion to two carbon-carbon triple bonds so that the co-ordination geometry is trigonal planar. The Pt atom geometry in both complexes is square planar. An electrochemical study of the copper complexes 2a and 2b reveals one fully reversible one electron reduction that is consistent with the first reduction of the co-ordinated bipyridyl ligand. There is also an irreversible one electron oxidation that corresponds to the CuI to CuII transition.

Dependence of Tc on hydrostatic pressure in beta?-(ET)2SF5CH2CF2SO 3 and kappa-(ET)2Cu(NCS)2

The dependence of Tc on hydrostatic (He-gas) pressure is determined for the recently discovered organic superconductor beta?-(ET)2SF5CH2CF2SO 3 [ET = bis(ethylenedithio)-tetrathiafulvalene] with Tc(0) ? 5 K, yielding the pressure derivative dTc/dP ? -1.34 K kbar-1. The present experiments also included kappa-(ET)2Cu(NCS)2 where we find the extremely large value dTc/dP ? -3.84 K kbar-1, in agreement with earlier studies. For both samples the pressure dependence Tc(P) does not depend on the temperature at which the pressure is changed.

Structural versatility and electronic structures of copper(i) thiocyanate (CuSCN)-ligand complexes

Copper(i) thiocyanate (CuSCN) is a promising semiconductor with an expansive range of applications already demonstrated. Belonging to the group of coordination polymers, its structure can be easily modified, for example via ligand (L) coordination. In this work, we have analyzed in detail the crystal structures of 26 CuSCN-L complexes that exhibit diverse structures changing from the 3D networks of the parent CuSCN to 2D sheet, 1D ladder, 1D zigzag chain, 1D helical chain, and a 0D monomer as well as intermediate bridged structures. We outline herein the basic structural design principles based on four factors: (1) Cu(i) geometry, (2) CuSCN?:?L ratio, (3) steric effects, and (4) supramolecular interactions. In addition, we employ density functional theory to study the electronic structures of these 26 complexes and find that the opto/electronic properties vary over a wide range, e.g., widened or reduced fundamental band gaps, restricted hole transport due to Cu-SCN network disruption, and the possibility of electron transport through the ligand states. We also observe a correlation between the electronic properties and the dimensionality of the Cu-SCN network. Lowering the dimensionality of the 3D structure to 2D, 1D, and 0D by increasing the number of coordinating ligands, the dispersion and the width of the top valence bands decrease whereas the energy difference between the Cu and SCN states expands. Aliphatic ligands in most cases do not generate electronic states in the band gaps whereas aromatic ligands give rise to states between the Cu and SCN states that lead to optical absorption and emission in the visible range. This study provides guidelines for developing coordination polymer semiconductors based on the Cu-SCN network. The 2D structure is identified as a promising platform for designing new CuSCN-based materials as it retains the carrier transport properties while allowing for properties tailoring through ligand coordination.
