A series of novel metal complexes were synthesized containing an Ir-cyclometalated bichromophore as a visible-light sensitizer. A new bichromophoric unit containing a naphthyl substituent and methyl substituents on the 2-phenylpyridine chelating ligand was synthesized and characterized for the first time. According to the increased crystallinity of the bichromophoric unit, novel Ir-M metal complexes (M = Pd, Mn, and Ir) were synthesized and fully characterized. The novel Ir-Pd complex maintained photocatalytic activity toward styrenes under visible-light irradiation, and polymerization with -chlorostyrene, copolymerization with styrene and -chlorostyrene furnished corresponding polymers.
一系列新型金属配合物被合成出来，其中包含一个作为可见光敏化剂的 Ir-环金属化双生色团。首次合成并表征了一个新型双生色团单元，该单元含有萘基取代基和 2-苯基吡啶螯合配体上的甲基取代基。根据双生色团单元的结晶度增加，合成并充分表征了新型 Ir-M 金属配合物（M = Pd、Mn 和 Ir）。新型 Ir-Pd 配合物在可见光照射下对苯乙烯保持光催化活性，并且与 -氯代苯乙烯聚合，与苯乙烯和 -氯代苯乙烯共聚得到相应的聚合物。
