【Abstract】 Electroluminecent polymer have attracted more and more attention from earily 90′s. Inherent applications in microelectrons, flat display and related fields accelerate its research and development. Problem to delay its industrial use are longterm stablity and effiency of electro optical transformation. Many researches focused on molecular design of poly(phenylene vinylene) to improve its processing and electroluminecent properties. Except introducing long alkyl groups into chain of PPV grafting and block copolymer containing PPV segments are prepared to improve its solubility in common organic solvents. Controlling the conjugated length of PPV unit the peak wavelength of light emitting shifted from yellow to blue. In this article, improvement and new trends about PPV and its analogues are reviewed.更多还原
