A series of new phosphorescent cyclometalated iridium(iii) complexes which possess aggregation-induced emission enhancement (AIEE) detect 2,4,6-trinitrophenol (TNP) selectively with high quenching constants in aqueous media. The sensing mechanism was systematically investigated by mass spectrometry, H and F NMR spectroscopy. X-ray crystal structure analysis reveals an O-HO interaction between TNP and the ancillary ligand which explains the high selectivity for TNP compared to other nitro-aromatics.
一系列具有聚集诱导发光增强（AIEE）特性的新型环金属化铱（III）配合物在水性介质中能够以高猝灭常数选择性地检测2,4,6-三硝基苯酚（TNP）。通过质谱、氢核磁共振和氟核磁共振光谱对传感机制进行了系统研究。X射线晶体结构分析揭示了TNP与辅助配体之间的O-HO相互作用，这解释了与其他硝基芳烃相比对TNP具有高选择性的原因。
