摘要
In this paper, we report a novel phosphorescent Re(1) complex of Re(CO)(3)(ETCP)Br, where ETCP=1-ethyl-2-naphthalen -1-yl-1H-1,3,7,8-tetraaza-cyclopenta[I]phenanthrene, including its photophysical properties, geometric/electronic structures, electrochemical and thermal properties. Experimental data suggest that Re(CO)(3)(ETCP)Br is a promising yellow emitter peaking at 540-nm with short excited state lifetime of similar to 0.06 mu s. Re(I) center localizes in a distorted octahedral field in Re(CO)(3)(ETCP)Br and the emissive state of Re(CO)(3)(ETCP)Br has metal-to-ligand-charge-transfer character, leading to the room-temperature phosphorescence. Further analysis reveals that Re(CO)(3)(ETCP)Br has HOMO and LUMO energy levels at -6.03 V and -3.56 V. respectively, as well as its high thermal decomposition temperature of 377 degrees C. Using Re(CO)(3)(ETCP)Br as a dopant, an electroluminescence peaking at 565-nm is realized, with a maximum luminance of 5900 cd/m(2) and a maximum current efficiency of 11.3 cd/A.
