A family of unsymmetrical donor–acceptor, ferrocenyl-substituted benzothiadiazoles of types D1–π–A−π–D2, D1–π–A1–π–A2, D1–A−π–D2, and D1–A1–A2–D2, bearing a variety of electron-donating and electron-withdrawing groups, were designed and synthesized. Their photophysical, electrochemical, and computational properties were explored, which show strong donor–acceptor interaction. The presence of electron-rich
D 1 –π–A–π–D 2,D 1 –π–A 1 –π–A 2,D 1 –A–π–D 2和D 1的不对称供体-受体,二茂铁基取代的苯并噻二唑家族。设计并合成了带有各种给电子基团和吸电子基团的D 1 -A 1 -A 2 -D 2。探索了它们的光物理,电化学和计算性质,显示出强的供体-受体相互作用。富电子单元蒽(6f)和三苯胺(6h)的存在),而缺电子单元1,1,4,4-四氰基-1,3-二烯(TCBD)(9b)导致带隙降低,这导致这些苯并噻二唑的吸收光谱发生红移系统。报道了6c,6g,7a和7b的单晶结构,显示出奇妙的超分子相互作用。
