Abstract

A methodology for the synthesis of monodisperse homoconjugated oligomers (dimer, trimer, and tetramer) derived from cofacial 7,7-diphenylnorbornane (DPN) is described. Extended aromatic homoconjugation is observed in these oligomers as revealed by the electronic spectra. The effective homoconjugation length (EHL) is in the range of 4-5 DPN subunits.

摘要

本文描述了一种合成源自共面7,7-二苯基降冰片烷（DPN）的单分散同共轭低聚物（二聚体、三聚体和四聚体）的方法。电子光谱显示，这些低聚物中存在扩展的芳香族同共轭现象。有效同共轭长度（EHL）在4至5个DPN亚基的范围内。
