Conjugated nanohoops allow studying the effect of cyclic conjugation and bending on the incorporated π-systems. To date, no such system containing antiaromatic units has been reported. We herein present [12]cycloparaphenylenes incorporating two dibenzo[,]pentalene units: [2]DBP[12]CPP nanohoops. Dibenzo[,]pentalene is a nonalternant hydrocarbon with antiaromatic character. The syntheses and optoelectronic properties of two different [2]DBP[12]CPP nanohoops with electronically modifying substituents are reported, accompanied by TDDFT calculations.
共轭纳米环有助于研究环状共轭和弯曲对所含π体系的影响。迄今为止，尚未报道过包含反芳香单元的此类体系。我们在此展示了含有两个二苯并[，]戊搭烯单元的[12]环对亚苯基：[2]DBP[12]CPP纳米环。二苯并[，]戊搭烯是一种具有反芳香特性的非交替烃。报道了两种具有电子修饰取代基的不同[2]DBP[12]CPP纳米环的合成及光电性质，并进行了含时密度泛函理论（TDDFT）计算。
