Two water-soluble anionic cyclometalated Ir(iii) complexes, Ir(ppy)2BPS [] and Ir(F-mppy)2BPS [] have been synthesized and display clear evidence of self-assembly in water. Concentration-induced aggregation enhances the excited-state properties of both complexes, blue-shifting the photoluminescence emission energies as well as increasing the corresponding excited state lifetimes and quantum yields up to a factor of 5.
已合成了两种水溶性阴离子环金属化铱（III）配合物，即Ir(ppy)2BPS [] 和Ir(F-mppy)2BPS []，并且它们在水中表现出明显的自组装迹象。浓度诱导的聚集增强了这两种配合物的激发态性质，使光致发光发射能量发生蓝移，同时将相应的激发态寿命和量子产率提高了5倍。
