A series of layered cyclophanes where an anthracene ring is stacked in different modes with the same or other π-systems has been synthesized by the Hofmann elimination method or photodesulfurization for studying the transannular π-electronic interaction. Photochemical and thermal interconversions have been observed between syn-(1,4)anthracenophane and its isomer and have been discussed with reference
通过霍夫曼消除法或光脱硫法合成了一系列层状环芳,其中蒽环以不同模式堆叠,具有相同或其他 π 系统,用于研究跨环 π 电子相互作用。已经观察到合成-(1,4) 蒽及其异构体之间的光化学和热相互转化,并参考 X 射线晶体数据进行了讨论。从电子光谱已经确定跨环相互作用随着两个面对的芳环之间的重叠而增加,并且当两个生色团之间的重叠相同时,相互作用相对于面对生色团的尺寸增加。
