中文摘要a series of conjugated blue-light-emitting copolymers, ptc-1, ptc-2, and ptc-3, comprised different ratios of electron-withdrawing segments (spirobifluorene substituted with cyanophenyl groups) and electron-donating segments (tricarbazole-triphenylamines), has been synthesized. the structures of these polymers were characterized and their thermal, photophysical, electrochemical, and electroluminescence properties were measured. incorporation of rigid spirobifluorene units into the copolymers led to blue-shifted absorption peaks in dilute toluene solution. cyclic voltammetric measurement indicated the bandgaps of the polymers were in the range of 2.77-2.94 ev. it was found that increasing cyanophenyl-spirobifluorene content in the polymer backbone lowered both the homo and lumo energy levels of the copolymers, which was beneficial for electron injection/transporting in the polymer layer of the device. oled device evaluation indicated that all the polymers emitted sky blue to deep blue light when the pure polymers were used as the emissive layers in the devices with a configuration of ito/pedot:pss/polymers/csf/ca/al. the devices have been optimized by doping 30 wt % pbd into the polymer layers. among the doped devices, ptc-2 showed the best performance with the turn-on voltage of 3.0 v, maximum brightness of 7257 cd/m(2), maximum current efficiency of 1.76 cd/a, and cie coordinates of (0.15, 0.14).
