Polymer-based tris(2-phenylpyridine)iridium complexes

摘要: A series of fac-Ir(ppy)3 complex functionalized poly(styrene)s and poly(N-vinylcarbazole)-co-poly(styrene)s were synthesized. The emission wavelength all polymers could be readily tuned from 550 to 515 nm by reducing the linkage Ir polymer backbones a Schiff base an amine. reduced retained photophysical properties corresponding small molecule fac-Ir(ppy)3, including transient absorption behaviors, high quantum yields (0.12−0.23), long excited-state lifetimes (963−1221 ns). These results clearly indicate that do not interfere with pendant chromophore but endow solution processability these materials for potential use in light-emitting devices emissive display technology.
