| 英文摘要 | Two new stepladder conjugated polymers, that is, poly(7,7,15,15-tetraoctyldinaphtho[1,2-a:1',2'-g]-s-indacene) (ponsi) and poly(7,7,15,15-tetra(4-octylphenyl)dinaphtho[1,2-a:1',2'-g]-s-indacene) (pansi) with alkyl and aryl substituents, respectively, have been synthesized and characterized. in comparison with poly(indenofluorene)s, both polymers have extended conjugation at the direction perpendicular to the polymer backbone because of the introduction of naphthalene moieties. the emission color of the polymers in film state is strongly dependent on the substituents. while ponsi emits at a maximum of 463 nm, pansi with the same backbone but aryl substituents displays dramatically redshifted emission with a maximum at 494 nm. both polymers show stable photoluminescence spectra while annealing at 200 degrees c in inert atmosphere. the ponsi-based devices with the configuration of ito/pedot:pss/polymer/ca/al turn on at 3.7 v, and emit at a maximum of 461 run with the cie coordinates of (0.19, 0.26), a maximum luminance efficiency of 1.40 cd/a, and a maximum brightness of 2036 cd/m(2) at 13 v meanwhile, the emission color of the devices is independent of driving voltage and keeps unchanged during the continuous operation.
