聚间亚苯亚乙烯的性能研究

自1990年Burroughes等首次报道聚对亚苯亚乙烯的电致发光以来，由于电致发光高分子材料在平面显示(特别是大面积显示)方面具有其他显示材料难以比拟的优势，因而近年来受到人们的广泛关注，在合成方法、加工性能、发光颜色的调控以及器件性能等多方面取得显著进展，不

SYNTHESIS AND PROPERTIES OF POLY(m-PHENYLENEVINYLENE)

Regioregular poly(1-butoxy-2,4-m-phenylenevinylene) was synthesized by Wittig reaction with salicylaldehyde as the starting material,and its properties were compared with poly(2,5-dibutoxy-1,4-p-phenylenevinylene-alter-p-phenylenevinylene) (Bu-PPV) and poly(2,5-dibutoxy-1,4-p-phenylenevinylene-alter-m-phenylenevinylene) (Bu-PMPV).The results showed that the introduction of m-phenylene could obviously improve the solubility.Thus,the solubility of Bu-PMPV was almost one order of magnitude higher than that of Bu-PPV,and Bu-MPV had a solubility 2～5 times of that of Bu-PMPV.The introduction of m-phenylene also caused obvious blue-shifts in the UV-Vis absorption and fluorescence spectra.The UV-Vis spectrum of Bu-MPV in CHCl 3 showed one absorption band λ max at 316、nm.The fluorescence of Bu-MPV solution in CHCl 3 exhibited a very narrow emission peak with emission maxima at about 419 and 434、nm,the full width at half-maximum of the emission peak is about 60、nm.
