thienyl-2-carboxylate (Th), 2,2'-bithienyl-5-carboxylate (BTh), and 2,2':5',5″-terthienyl-5-carboxylate (TTh). The compounds have been characterized by proton nuclear magnetic resonance ((1)H NMR), ultraviolet-visible (UV-vis) absorption and emission, differential pulse voltammetry, and time-resolved transient absorption and infrared (IR) spectroscopy. An X-ray crystal structure was obtained for the thienyl
已经制备了化合物顺式-Mo2(DAniF)2(L)2,其中 DAniF = (N,N')-p-二甲脒基和 L = 噻吩基-2-羧酸酯 (Th), 2,2'-二噻吩基- 5-羧酸盐 (BTh) 和 2,2':5',5"-terthienyl-5-carboxylate (TTh)。这些化合物已通过质子核磁共振 ((1) H NMR)、紫外-可见 (UV-vis) 吸收和发射、差分脉冲伏安法以及时间分辨瞬态吸收和红外 (IR) 光谱进行表征。获得了噻吩基配合物的 X 射线晶体结构。相关的盐 [(n)Bu4N]2[Mo2(DAniF)2(TTh-CO2)2],其中 TTh-CO2 = 2,2':5',2"-terthienyl-5,5"-dicarboxylate,具有还制备并用于将复合物附着到 TiO2 纳米颗粒上。后者已通过基态傅里叶变换红外光谱 (FTIR) 和飞秒时间分辨红外光谱进行表征。时间分辨数据为从
