Abstract

The preparation and crystal structures of 3,3''-diethynyl-2,2':5',2''-terthiophene (A(2)T(3)) and three Au(I) complexes containing this ligand are reported. One of the complexes, Au(2)(dppm)(A(2)T(3)), has a short Au-Au distance (3.1969 A) because of an aurophilic interaction. UV/vis absorption and emission spectra of the complexes and ligand at 298 and 85 K and photoinduced electron transfer to methyl viologen are reported. A(2)T(3) and two of the complexes may be electropolymerized, and the resulting gold-containing films were characterized by X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry.

摘要

报道了 3,3''-二乙炔基-2,2':5',2''-三联噻吩（A(2)T(3)）的制备及其晶体结构，以及三种含有该配体的金（I）配合物。其中一个配合物，Au(2)(dppm)(A(2)T(3))，由于金-金相互作用，具有较短的 Au-Au 距离（3.1969 A）。报道了配合物和配体在 298 和 85 K 下的紫外/可见吸收和发射光谱以及向甲基紫精的光致电子转移。A(2)T(3)和两个配合物可能发生电聚合，所得含金薄膜的特性通过 X 射线光电子能谱（XPS）和循环伏安法进行了表征。
