multifunctional ligands and precursors for molecular materials, have been synthesized by copper‐ or ruthenium‐based “click” chemistry. The solid‐state structures of three ligands and two CuII complexes were determined. Large differences in the electron‐donating properties between the 1,4‐ and 1,5‐isomers were evidenced by cyclic voltammetry. Theoretical calculations support this observation and allow the assignment
通过基于铜或钌的“喀哒”化学反应合成了两个系列的4-和5-四硫富瓦烯基-1,2,3-三唑,它们是分子材料的多功能配体和前体。确定了三个配体和两个Cu II配合物的固态结构。通过循环伏安法证明了1,4和1,5-异构体之间的供电子性质存在很大差异。理论计算支持该观察,并允许分配在配体的UV / Vis光谱中观察到的电子跃迁。
