Abstract

Cette invention concerne un polymère (par ex., polymère photocatalytique) qui contient des motifs chromophores (par ex., couplés par covalence, dans le squelette et/ou les chaînes latérales du polymère). Dans certains modes de réalisation, le polymère comprend : (a) un premier ligand à titre de premier motif monomère répétitif (par ex., faisant partie du squelette et/ou des chaînes latérales du polymère) ; (b) un métal de transition (par ex., Ru, Ir, Fe, Co, etc.) formant un complexe avec ledit premier ligand pour constituer un motif chromophore ou un photocatalyseur de type métal de transition avec celui-ci ; et (c) éventuellement, mais de préférence, au moins un ligand supplémentaire (par ex., un ou deux) formant un complexe avec ledit métal de transition pour constituer ledit motif chromophore ou photocatalyseur de type métal de transition ; et (d) éventuellement, mais de préférence, un second motif monomère copolymérisé avec ledit premier motif monomère. Des compositions le contenant et des procédés pour l'utiliser sont également décrits.
