As an extension of the authors’ previous study, three sky-blue homoleptic Ir(III) complexes 1-3 with F-free phenylimidazole ligands were synthesized and their photophys., electrochem. and thermal properties were studied. All the complexes showed high photoluminescence quantum yields ranging from 0.50 to 0.53. The introduction of a bulky iso-Pr group at the 2,6-position of N-Ph of the phenylimidazole ligands increases the quantum yield and the decomposition temperature of the IR(III) complexes. As the conjugated system of the ligand becomes larger, a very small bathochromic-shift of 1 nm was observed in complex 3 (475 nm) compared with complexes 1 (474 nm) and 2 (474 nm). All the OLED devices showed high current efficiencies of over 20 cd A-1 at the luminance of 1000 cd m-2. Devices incorporated with complexes 1-3 all showed longer lifetime in comparison with that of a FIrpic-based device. This study involved multiple reactions and reactants, such as 1-(2,6-Diisopropylphenyl)-2-phenyl-1H-imidazole (cas: 914306-50-6Application of 914306-50-6).
1-(2,6-Diisopropylphenyl)-2-phenyl-1H-imidazole (cas: 914306-50-6) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Application of 914306-50-6
