Mesityl derivatives of the unknown dibenzopentalene isomer dibenzo[a,f]pentalene were synthesized. The molecular geometry and physical properties of dibenzo[a,f]pentalene were investigated. Dibenzo[a,f]pentalene combines a large antiaromatic and appreciable singlet open-shell character, properties not shared by well-known isomer dibenzo[a,e]pentalene.
合成了未知二苯并戊烯异构体二苯并[a,f] 戊烯的甲基衍生物。研究了二苯并[a,f]戊烯的分子几何结构和物理性质。二苯并[a,f]戊烯结合了大的抗芳香性和明显的单线态开壳特性,这是众所周知的异构体二苯并[a,e]戊烯所不具备的特性。
