Synthesis and Characteration of Novel Phosphorescent Green Light-emitting Copolymers with Different Triplet Energy host units |
| 초록 |
Three series of new green iridium light-emitting electrophosphorescent polymers with fluorene and carbazole as triplet energy main chain were synthesized via Yamamoto polymerization, respectively. The molecular structures of the polymers were characterized with 1H NMR spectroscopy and their photophysical, electrochemical and electroluminescence properties were investigated. Note that as increasing the ratio of iridium complex in the polymer, obvious red-shift was observed due to efficient energy transfer from host to dopant component. In this series of copolymers, external quantum efficiency of 0.67, a maximum luminous efficiency of 1.24 cd/A and a maximal luminance of 615.2 cd/m2 were observed and the maximum EL peak at 528 nm was obtained in the 15 mol% iridium complex device. |
