The synthesis and characterisation of six new cationic iridium(III) complexes bearing either 4,4′-di-tert-butyl-2,2′-bipyridine (dtBubpy) or 5-NO2-1,10-phenanthroline along with two cyclometallated 2-phenylpyridine derivative ligands, decorated with triphenylamine groups either meta or para to the Ir–CC^N bond or para to the Ir–NC^N bond, are reported. The second-order nonlinear optical (NLO) properties
六种带有4,4'-二叔丁基-2,2'-联吡啶(d t Bubpy)或5-NO 2 -1,10-菲咯啉的新型阳离子铱(III)配合物的合成与表征2环金属化2-苯基吡啶衍生物配位体,缀以三苯胺基或者间位或者对位到IR-C C ^ N键或对位到IR-N C ^ N键被报告。二阶非线性所有化合物的光学(NLO)性质已经通过诱导二次谐波生成技术和显示,该电场确定μβ EFISH可以通过铱配位球的性质来调整其价值。偶极矩,μ,必要评估二次超极化率β EFISH,从理论上确定。还给出了配合物的线性光学性质,并通过量子化学计算对其进行了合理化。将制备的一种铱化合物掺入聚苯乙烯薄膜中,提供了基于阳离子有机金属配合物的二阶NLO活性聚合物薄膜的第一个实例。
