respectively. Their photophysical properties have been investigated and compared. The results have shown that complex 2 is aggregation-induced phosphorescent emission (AIPE) active and exhibits the highest photoluminescent quantum yield (PLQY) of 16.2% in neat film among the reported cationic Ir(III) complexes with AIPE activity. In addition, it also enjoys redox reversibility, good film-forming ability
我们报告的合成和表征与树枝状的两个阳离子铱(III)配合物。咔唑配体作为辅助配体,即[Ir(ppy)2 L3] PF 6(1)和[Ir(ppy)2 L4] PF 6(2),其中L3和L4表示3,8-双(3,6-二叔丁基-9 H-咔唑-9-基)-1,10-菲咯啉 和 3,8-双(3',6'-二叔丁基-6-(3,6-二叔丁基-9 H-咔唑-9-基)-3,9'-bi(9 H -咔唑)-9-基)-1,10-菲咯啉, 分别。已经对其光物理性质进行了研究和比较。结果表明,在报道的具有AIPE活性的阳离子Ir(III)配合物中,配合物2具有聚集诱导的磷光发射(AIPE)活性,在纯净膜中显示出16.2%的最高光致发光量子产率(PLQY)。此外,它还具有氧化还原可逆性,良好的成膜能力,出色的热稳定性以及开/关发光转换特性,显示出其潜在用途,可作为发光电化学电池和有机蒸气感测的候选材料。为了探索在生物学中的应用,使用2对细胞进行成像。
