The ground state and low-lying excited electronic states in the Ir(III) complex fac-Ir(ppz) 3 are studied using density functional theory where ppz=phenylprazol and fac=facial. We reported before that this complex was pure blue phosphorescent material with about 450 nm of electroluminescent peak. Herein, the electronic properties of the molecule are studied using the B3LYP functional and the...
We have studied the new blue electroluminescent material (compound 1) synthesized from the reaction of 2-(2-hydroxyphenyl)benzoxazole with LiBH 4 according to Tao's procedure [J. Am. Chem. Soc. 121 (1999) 9447; Appl. Phys. Lett. 75 (1999) 1665] Compound 1 showed the UV and the PL peak at 366 and 432 nm, respectively. The manufactured device (ITO/compound 1(600 A)/Al) showed the EL peak at...
