Copper ions (Cu2+) play an indispensable role in both the human body and eco-environment, so it is crucial to create simple, highly sensitive and selective sensors to recognize Cu2+ ions. In this work, three efficient iridium(III) complexes, [(L1)2Ir(Czdtc)] (Ir1, L1 = 6-phenylnicotinaldehyde), [(L2)2Ir(Czdtc)] (Ir2, L2 = 6-(4-(trifluoromethyl)phenyl)nicotinaldehyde) and [(L3)2Ir(Czdtc)] (Ir3, L3 =
铜离子(Cu 2+ )在人体和生态环境中都发挥着不可或缺的作用,因此构建简单、高灵敏度和选择性的传感器来识别Cu 2+离子至关重要。在这项工作中,三种高效的铱 ( III ) 配合物,[(L 1 ) 2 Ir(Czdtc)] ( Ir1 , L 1 = 6-苯基烟醛), [(L 2 ) 2 Ir(Czdtc)] ( Ir2 , L 2 = 6-(4-(三氟甲基)苯基)烟醛)和[(L 3 ) 2 Ir(Czdtc)] ( Ir3 , L 3= 6-(4-甲氧基苯基)烟醛) 包含四元 Ir-S-C-S 环主链和 9 H-咔唑-9-硫代碳酸酯 (Czdtc) 作为辅助配体,在室温下在 10 分钟内合成,并且开发为高效化学传感器来检测 Cu 2+离子。Ir1–Ir3表现出峰值在 575 和 593 nm 之间的宽发射带,PLQY 在 0.34–0.70 范围内,寿命范围在 1.3 至 1.8 μs
