摘要Two blue luminescence materials 2-phenyl-1H-phenanthro[9,10-d] imidazole (Phen-PI) and 2-pyridin-2-yl-1H-phenanthro[9,10-d] imidazole (Pyri-PI) were synthesized. The photophysical properties demonstrated the emission peaks of Phen-PI and Pyri-PI are 371.5, 388.5 and 403.5 nm, the photoluminescent quantum yield is 0.383 and 0.528, the fluorescence decay lifetime is 3.87 ns and 3.68 ns. The Frontier molecular orbital compositions and distribution for Phen-PI and Pyri-PI were calculated by using density functional theory (DFT). The results indicate that the introduction of pyridyl group to phenanthro[9,10-d] imidazole makes HOMO and LUMO of Pyri-PI decline 0.09 eV and 0.23 eV respectively, the energy gap between HOMO and LUMO decrease 0.14 eV, which can explaine the red-shift of Pyri-PI emission in theory. 2016, Science Press.
