摘要

强共轭体系中的脱ocalization效率仍然是调节与其范围直接相关的光学特性的一个重要因素。一种具有电子捐赠/接受功能的正交取代亚苯基衍生物被内置到一个完全不饱和的大环系统中，该系统具有二向和/或旁向电流的全局脱焦功能。精确定位的结构修饰影响了光谱参数中的观察行为，这些参数在 4n+2 系统中仅有轻微的可识别性，但对具有 4n π 电子脱定位路径贡献的还原衍生物却有重大影响。

Conjugation Paths in Oxatriphyrin(2.1.1) - C2 Bridge Modifications.

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.

期刊介绍： ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
