A new isomer: 11,12‐Dimesitylindeno[2,1‐a]fluorene was synthesized and isolated in crystal form. The indenofluorene exhibits significant bond‐length alternation in the o‐quinodimethane structure, limited singlet biradical character, and weakly antiaromatic character. Optical and electrochemical properties suggest that indeno[2,1‐a]fluorene derivatives may be candidates for optoelectronic materials
合成了一种新的异构体:11,12-二甲双胍[2,1- a ]芴,并以晶体形式分离出。茚并芴在邻喹啉甲烷结构中具有明显的键长交替,有限的单线双自由基特性和弱的芳香性。光学和电化学性质表明,茚并[2,1- a ]芴衍生物可能是光电子材料的候选者。
