摘要: 聚-4-重氮基苯乙烯(PDS)在碱性水溶液下通过与Na2SO3反应,制备了聚-4-偶氮磺酸基苯乙烯(PDSS).作为负离子聚电解质PDSS能与四-(三甲氨基苯基)-卟啉(TTMAP)通过离子相互作用进行层-层自组装.光照下该组装膜中的离子键转变为共价键,结果是组装膜对极性溶剂和盐水溶液变为非常稳定,从而能直接在KCl水溶液中测定其光电流.结果表明,该组装膜具有良好的光电转换性质.

Abstract: Poly(diazosulfonate styrene)(PDSS) was synthesized with reaction of poly(diazonium styrene)(PDS) and Na2SO3 in an alkali aqueous solution.As an anionic polyelectrolyte PDSS can self-assemble(SA) with tetra-trimethylaminophenylporphyrin(TTMAP) layer-by-layer via ionic interaction. Under UV irradiation the ionic bonds of the film convert into covalent bonds resulting in the film becoming very stable towards polar solvents or salty aqueous solutions and can determine its photocurrent directly in KCl aqueous solution.The results show that the film possesses good photoelectron conversion properties.

Key words: poly(diazo-sulfonate styrene), tetra-trimethylaminophenylporphyrin, self-assemble, photo-electron conversion
