含有[Mn(bipy)3]2+(bipy = 2,2′-联吡啶)和[MIL(diene)]+(M = Rh或Ir，L = 2,2′-联吡啶或1,10-菲咯啉，二烯=环辛塔-1,5-二烯或norborna-2,5-二烯)类型的新型功能化聚吡咯薄膜已被合成并通过电化学表征技术和紫外/可见光谱。该策略基于聚合物薄膜中 Mn2+ 阳离子和 [{MI(diene)Cl}2] 前体络合物的络合，通过吡咯取代的 2,2'-联吡啶和 1,10-菲咯啉单体在酸性 MeCN 电解质中的氧化电聚合涂覆在铂和碳电极上。聚[MIL(二烯)+]的氧化还原行为强烈依赖于支持电解质的阳离子的大小。这似乎是其渗透薄膜以维持聚合物电中性的结果。
New functionalized polypyrrole films containing transition-metal complexes of the type [Mn(bipy)3]2+(bipy = 2,2′-bipyridine) and [MIL(diene)]+(M = Rh or Ir, L = 2,2′-bipyridine or 1,10-phenanthroline, diene = cycloocta-1,5-diene or norborna-2,5-diene) have been synthesized and characterized by electrochemical techniques and UV/VIS spectroscopy. The strategy is based on the complexation of Mn2+ cations and [{MI(diene)Cl}2] precursor complexes in polymer films, coated on platinum and carbon electrodes by oxidative electropolymerization of pyrrole-substituted 2,2′-bipyridine and 1,10-phenanthroline monomers in acidic MeCN electrolyte. The redox behaviour of poly[MIL(diene)+] is strongly dependent on the size of the cation of the supporting electrolyte. This appears to be a consequence of its permeation through the film to maintain electroneutrality in the polymer.
