In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Preparation of 8-hydroxyquinoline aluminum nanomaterials to enhance properties for green organic light-emitting diode devices, published in 2021-06-30, which mentions a compound: 2085-33-8, Name is Aluminum triquinolin-8-olate, Molecular C27H18AlN3O3, Recommanded Product: 2085-33-8.
Tris(8-hydroquinoline) aluminum (Alq3) plays an important role in the applications of green organic light-emitting diodes (OLEDs). In this paper, Alq3 nanofilms were prepared on glass substrates by phys. vapor deposition system with different surface states. The structures and morphologies of Alq3 nanofilms were characterized by X-ray diffractometer and scanning electron microscope. Alq3 nanomaterials were used as the main luminescent material for green OLED devices. The structure of the green OLED is Mo/2-TNATA (20 nm)/NPB (10 nm)/Alq3 (25 nm):Ir(ppy)3 (5%)/Bphen (10 nm)/LiF (5 nm)/Mg:Ag (10%) (10 nm). The photoelec. properties of green OLED devices were characterized by the system of Photo Research PR655 spectrometer. The results show that the weak interactions among Alq3 mols. such as π-π bond interactions and van der Waals forces caused mols. self-assembling into nanospheres, nanospherical chains, nanowires, or nanotubes in phys. vapor deposition system. Precise surface state control of Alq3 nanomaterials can be realized by controlling the deposition temperature, thus, to enhance properties for green OLED displays. It is found that among different morphologies, Alq3 nanotubes have been proved to be the best green OLED devices with the brightness of 11,490 cd/m2, CIE (3358, 0.6302) at 5 V, and the current efficiency is 20.24 cd/A.
