Abstract

Herein, we show that twisted molecular nanoribbons with as many as 322 atoms in the aromatic core are efficient gelators capable of self-assembling into ordered π-gels with morphologies and sol-gel transitions that vary with the length of the nanoribbon. In addition, the nanoribbon gels show a red fluorescence and also pseudoconductivity values in the same range as current state-of-the-art π-gels.

摘要

在此，我们表明，芳香核中含有多达322个原子的扭曲分子纳米带是高效的凝胶剂，能够自组装成有序的π凝胶，其形态和溶胶-凝胶转变随纳米带长度而变化。此外，纳米带凝胶呈现红色荧光，并且其假电导率值与当前最先进的π凝胶处于同一范围。
