| 中文摘要 | the complexes [cu(dnpb)(dpephos)](+)(x-) (dnpb and dpephos are 2,9-di-n-butyl-1,10-phenanthroline and bis[2-(diphenyl-phosphino)phenyl]ether, respectively, and x- is bf4-, clo4-, or pf6-) can form high quality films with photoluminescence quantum yields of up to 71 +/- 7%. their electroluminescent properties are studied using the device-structure indium tin oxide (ito)/complex/metal cathiode. the devices emit green light efficiently, with an emission maximum of 523 nm, and work in the mode of light-emitting electrochemical cells. the response time of the devices greatly depends on the driving voltage, the counterions, and the thickness of the complex film. after pre-biasing at 25 v for 40 s, the devices turn on instantly, with a turn-on voltage of ca. 2.9 v. a current efficiency of 56 cd a(-1) and an external quantum efficiency of 16% are realised with al as the cathode. using a low-work-function metal as the cathode can significantly enhance the brightness of the device almost without affecting the turn-on voltage and current efficiency. with a ca cathode, a brightness of 150 cd m(-2) at 6 v and 4100 cd m(-2) at 25 v is demonstrated. the electroluminescent performance of these types of complexes is among the best so far for transition metal complexes with counterions. |
