英文摘要	A new series of polyquinoline copolymers (P1-P5) containing 9,9'-spirobifluorene in the main chain were synthesized via Friedlander reactions. The emission colors of the polymers were readily tuned from blue to yellow by changing the conjugated counits. Excellent EL performances were obtained for P5, probably because the proper donor/acceptor pairs were rightly matched, and the charge transport was significantly balanced. The devices based on P5 showed a maximum external quantum efficiency of 0.63% and a maximum photometric efficiency of 1.85 cd/A (at a brightness of 140 cd/m(2)). Yellow-green EL with narrow full width at the half-maximum (fwhm < 70 nm) and the highest maximum luminance (1768 cd/m(2)) among the currently reported polyquinolines was obtained for P5.
