中文摘要three new iridium compounds, 4-f-firpic, 4-cl-firpic and 4-br-firpic, were designed and synthesized by introducing the f, cl and br atoms to the 4-position of pyridine ring in the frame of sky-blue emitter, firpic. adding f atom stabilizes the homo level of firpic but keeps the lumo level of firpic almost unchanged, which consequently broadens the homo-lumo gap of firpic and finely tunes the emission to 465 nm of 4-f-firpic from 470 nm of firpic. in contrast, introducing of cl and br atoms simultaneously lowers the homo and lumo levels of firpic, which brings about the squeeze of homo-lumo gap in firpic and makes the emissions of 4-cl-firpic and 4-br-firpic red-shift to 475 and 479 nm, respectively. the phosphorescent organic light-emitting devices using the three iridium compounds as dopants were fabricated with the following configuration: ito/moo3/tapc/tcta: dopants/tm/lif/al. the device based on 4-f-firpic showed a blue emission with the commission internationale de l'eclairage coordinate of (0.15, 0.28), and revealed rather high efficiencies, with maximum current efficiency of 29 cd a(-1), power efficiency of 29 lm w-1 and external quantum efficiency of 14.6%.
