| 英文摘要 | We presented the optical properties of a novel block copolymer containing chromophores, 2,5-dimethoxy-1,4-di(alpha-(2-naphthalene vinylene)benzene (MDNVB) and spacers, tri(ethylene oxide) (TEO). The intrachain and interchain excitations due to the molecular aggregation arc responsible for the significant bathochromic shift in the photoluminescence (PL) spectrum when going from the solution to the thin film. With a certain content of the polymer electrolyte, blue-green light-emitting electrochemical cell based on this block copolymer was demonstrated with the turn-on voltage of 2.5 V, the maximum electroluminescence (EL) efficiency of 1.2 cd/A, and the d.c. response time of less than 5 sec, indicating strongly that an improved morphology of the active layer is formed because of the effective TEO-PEO interaction. Lowering the content of the polymer electrolyte results in a higher turn-on voltage and smaller injection current, increasing the content leads to a considerable microscopic leaking current and lower EL efficiency of the device.
