| 摘 要： | 以4-(苯并[d]噻唑-2-基)-N,N-二甲基苯胺(1)、L-丝氨酸作为主配体和辅助配体，合成了一种新型环金属铱配合物(2)，所有化合物的结构通过1H NMR、MS和IR进行了表征确认。通过紫外吸收光谱和荧光发射光谱研究了铱配合物(2)的光物理性质，并采用含时密度泛函理论(TDDFT)对其最低能量电子跃迁和最低三重激发态进行了计算。而且铱配合物(2)的荧光发射光谱可选择性地被汞离子猝灭，暗示着此配合物可作为一种高效的turn-off型汞离子磷光传感器。

| Abstract: | A new bis-cyclometalated iridium complex (2) was synthesized using 4-(benzo[d]thiazol-2-yl)- N,N-dimethylaniline as main ligand (1) and L-serine as ancillary ligand, and its structure was fully characterized by 1H NMR, MS and IR. Its photophysical properties were studied by UV-Vis absorption and photoluminescence spectra. The lowest-energy electronic transitions and the lowest triplet excited states were calculated with time-dependent DFT (TDDFT). The emission of iridium complex (2) can be selectively quenched by Hg2+ ion. This suggests that the complex could be an excellent turn-off phosphorescent sensor for Hg2+ ion. |
