富勒烯主客体结构由于其分子水平的杂化排列而引起了越来越多的关注。然而，使用简单的咔唑衍生物与富勒烯结合的情况很少见。在这项研究中，合理设计了三种新型咔唑衍生物，含有可调节的桥联体和用于捕获富勒烯的咔唑单元。与一般的凹凸相互作用不同，富勒烯可以与平面咔唑亚基相互作用形成二维六边形/四边形共晶，具有1:1或1:2化学计量交替堆积模式，以及可控的富勒烯堆积模式。同时，当连续的C60中心点C60相互作用通道存在时，实现了良好的电子传输性能和显着的光伏效应。结果表明，将这种咔唑系统引入富勒烯受体将为新型富勒烯主客体结构的多功能应用提供新的见解。
Fullerene host-guest constructs have attracted increasing attention owing to their molecular-level hybrid arrangements. However, the usage of simple carbazolic derivatives to bind with fullerenes is rare. In this research, three novel carbazolic derivatives, containing a tunable bridging linker and carbazole units for the capturing of fullerenes, are rationally designed. Unlike the general concave-convex interactions, fullerenes could interact with the planar carbazole subunits to form 2-dimensional hexagonal/quadrilateral cocrystals with alternating stacking patterns of 1: 1 or 1: 2 stoichiometry, as well as the controllable fullerene packing modes. At the meanwhile, good electron-transporting performances and significant photovoltaic effects were realized when a continuous C60 center dot center dot center dot C60 interaction channel existed. The results indicate that the introduction of such carbazolic system into fullerene receptor would provide new insights into novel fullerene host-guest architectures for versatile applications.
