A series of C-shaped, 1,1â²-alkyl-bridged 4,4â²-diaryl-2,2â²-bibenzimidazoles has been synthesized. The crystal structures of these compounds have been determined and packing diagrams demonstrate that these molecules either form linear intercalated molecular chains or include solvent molecules in the solid state. Crystal structures are compared to computational structures determined using density functional theory, with the BMK/DZV(2d,p) method. The C-shaped or tweezer-like geometry enables them to act as building blocks for supramolecular architectures.
合成了一系列C形的1,1′-烷基桥联4,4′-二芳基-2,2′-双苯并咪唑。已确定这些化合物的晶体结构,堆积图显示这些分子在固态下要么形成线性插层分子链,要么包含溶剂分子。晶体结构与使用密度泛函理论(DFT)通过BMK/DZV(2d,p)方法确定的计算结构进行了比较。C形或夹具样几何结构使它们能够作为超分子体系的构建块。
