A novel ternary 2-(2-carboxylphenyl)imidazo[4,5-f]-1,10-phenanthroline-based europium(III) 2-thenoyltrifluoroacetonate complex with red luminescence was designed and prepared for anion recognition. Spectroscopic studies, including UV-vis, fluorescence and NMR, showed that the sensor exhibited striking emission changes in response to fluoride (green), hydrogen sulfate (blue) and acetate anions (pale blue) due to hydrogen bonding and competitive coordination with the Eu(III) ions.
一种新型三元 2-(2-羧基苯基)咪唑并[4,5-f]-1,10-菲咯啉铕(III)2-噻吩甲酰三氟丙酮配合物具有红色发光，用于阴离子识别。光谱研究，包括紫外-可见、荧光和 NMR，表明该传感器由于氢键和与 Eu(III)离子的竞争配位，对氟化物（绿色）、硫酸氢盐（蓝色）和醋酸盐阴离子（淡蓝色）表现出显著的发射变化。
