The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 1111-67-7, Name is Cuprous thiocyanate, belongs to copper-catalyst compound, is a common compound. Recommanded Product: 1111-67-7In an article, once mentioned the new application about 1111-67-7.
The title compounds [Et4N]2[MS4Cu4(SCN)4(2-pic)4] (M = W l, Mo 2) have been synthesized by the reaction of (Et4N)2MS4, Cu(SCN) and 2-picoline (2-pic, 2-methylpyridine). Single crystal X-ray diffraction data show that the anion clusters [MS4Cu4(SCN)4(2-pic)4]2 have the planar ‘open’ structure with four Cu atoms in three kinds of coordination modes. Nonlinear optical properties of these two clusters are investigated with a 8 ns pulsed laser at 532 nm. The two clusters exhibit large optical limiting performance, with limiting threshold values of 0.3 J cm2 for 1, 0.5 J cm2 for 2, and self-defocusing effects, effective nonlinear refractive index /;2 = -6.84 x 1012 esu (esu = 7.162 x 10 m5 v2) 1 and 2 = -8.48 x 1012 esu 2 respectively. Both compounds show reverse saturable absorption: a2 = 3.1 x l(T6 m W1 for 1 and a2 = 3.2 x 106 m W’ for 2 in 6.98 x 104 mol dm3 and 7.44 x 10 mol dm3 DMF solution respectively. The corresponding effective NLO susceptibilities %m are 6.5 x 108 esu 1 and 8.9 x 108 esu 2 while the corresponding hyperpolarizabilities (y(I) = 9.42 x 1032 esu and ym = 1.29 x 1031 esu) are also reported.
