共辄纳米环允许研究环状共辄和弯曲对并入的π-系统的影响。到目前为止，还没有这样的系统包含反芳环单元的报道。我们在本文中提出了[12]结合两个二苯并[a，e]并环戊二烯单元的环对苯撑：[2]DBP[12]CPP纳米环。二苯并[a，e]并环戊二烯是一种具有反芳烃性质的非交替烃。报道了两种不同的含电子修饰取代基的[2]DBP[12]CPP纳米环的合成和光电性质，并进行了TDDFT计算。
Conjugated nanohoops allow to study the effect of cyclic conjugation and bending on the incorporated π-systems. Up to date, none such system containing antiaromatic units has been reported. We herein present [12]cycloparaphenylenes incorporating two dibenzo[a,e]pentalene units: [2]DBP[12]CPP nanohoops. Dibenzo[a,e]pentalene is a non-alternant hydrocarbon with antiaromatic character. The synthesis and optoelectronic properties of two different [2]DBP[12]CPP nanohoops with electronically modifying substituents are reported, accompanied by TDDFT calculations.
