11,11,12,12-Tetracyano-9,10-anthraquinodimethane (TCNAQ) derivatives having four types of aryl substituents, phenyl, biphenyl-4-yl, thien-2-yl, and 2,2′-bithiophen-5-yl groups at their 2-position, were synthesized and characterized. Their crystal structures were determined by single-crystal X-ray structure analysis, revealing that the TCNAQ moiety and electron-donating substituents form donor–acceptor-segregated columnar structures. The combination of nonplanar electron acceptor TCNAQ and planar donor units provides a good way to afford segregated columnar structures.
具有四种芳基取代基的11,11,12,12-四氰基-9,10-蒽醌二甲烷(TCNAQ)衍生物:苯基、联苯基-4-基、噻吩-2-基和2,2'-联噻吩-5-合成并表征了其2-位上的基团。通过单晶 X 射线结构分析确定了它们的晶体结构,表明 TCNAQ 部分和供电子取代基形成供体-受体分离的柱状结构。非平面电子受体 TCNAQ 和平面供体单元的组合提供了一种提供分离柱状结构的好方法。
