The synthesis and photophysical properties of luminescent Re(i) tricarbonyl complexes prepared from bis(pyridyl)- and bis(quinolyl) tetraarylethylene (TAE) ligands are reported. Emission wavelengths of the complexes are influenced by structural variation in the tetraarylethylene ligands, and several complexes display aggregation-induced enhanced emission in aqueous solution. A Re(i) complex prepared from an indole-functionalized TAE ligand shows significant enhancement in its luminescence intensity accompanied by a remarkable blue shift (∼95 nm) upon specific binding to site II of human serum albumin.
本文报道了由双（吡啶基）-和双（喹啉基）四芳基乙烯（TAE）配体合成的发光 Re(i) 三羰基配合物的合成及光物理性质。配合物的发射波长受四芳基乙烯配体结构变化的影响，一些配合物在水溶液中显示出聚集诱导增强发射。由吲哚功能化 TAE 配体制备的 Re(i) 配合物在与人血清白蛋白 II 结合时，其发光强度显著增强，同时伴随显著的蓝移（约 95nm）。
