eliminating lactam bridges from a soluble acene precursor through a retro‐Diels–Alder reaction, led to the synthesis and characterization of a novel, stable, green crystalline 6,8,10,17,19,21‐hexaphenyl‐1.22,4.5,11.12,15.16‐tetrabenzononatwistacene. An analysis of the single crystal structure of the nonatwistacene indicates that this molecule is twisted at an angle of 25.44°.
一种干净的反应策略,其基础是通过逆Diels-Alder反应从可溶性并苯前体中消除内酰胺桥,从而合成并表征了新颖,稳定的绿色结晶6,8,10,17,19,21-六苯基-1.22,4.5,11.12,15.16-四苯并壬基并四苯。对九碳四烯并苯的单晶结构的分析表明,该分子以25.44°的角度扭曲。
