An efficiency of delocalization in strongly conjugated systems remains an important factor crucial for modulation of the optical properties directly correlated with its range. An ortho-substituted phenylene derivative bearing electron donating/accepting functionality was built-in a fully unsaturated macrocyclic system with a global delocalization of a diatropic and/or a paratropic current. A precisely located structural modification influence observed behaviour in spectroscopic parameters that are only slightly recognizable in 4n+2 systems but showing a significant influence on the reduced derivatives with a contribution of 4n π-electrons delocalization path.
在强共轭体系中，离域效率仍然是一个重要因素，对于直接与其范围相关的光学性质的调制至关重要。一种带有供电子/吸电子官能团的邻位取代亚苯基衍生物被构建在一个完全不饱和的大环体系中，具有抗磁和顺磁电流的全局离域。精确的结构修饰影响了光谱参数中的观测行为，这些行为在4n+2体系中只是略有体现，但对具有4n π电子离域路径贡献的还原衍生物显示出显著影响。
