采用Wittig反应合成了一种分子主链上烷氧基取代刚性共轭聚对苯乙炔 (PPV)链段与柔性聚氧化乙烯 (PEO)链段交替排列的、可溶于氯仿与四氢呋喃等普通有机溶剂的新型结构的聚对苯乙炔类功能性发光共聚物EO -PPV。采用FT -IR、1H -NMR、DSC、GPC、元素分析等手段对共聚物进行了表征 ,并制备了结构为 (Al)Ca/EO -PPV/ITO的单层电致发光器件 ,器件的最大发光波长位于 475nm(蓝光 )。
Wittig reaction was used to synthesize an alternating chain of alkoxy-substituted rigid conjugated poly (p-phenylenevinylene) (PPV) segments and flexible polyethylene oxide (PEO) segments in the main chain of the molecule, which were soluble in common organic solvents such as chloroform and tetrahydrofuran Solvent novel structure of p-phenylacetylene functional luminescent copolymer EO -PPV. The copolymers were characterized by FT-IR, 1H-NMR, DSC, GPC and elemental analysis. The single-layer electroluminescent devices with (Al) Ca / EO-PPV / The emission wavelength is at 475nm (blue light).
