手性共轭超分子组装体，特别是手性超分子纳米结构，由于其显著的光电性质和在新一代有机半导体中的应用前景，引起了人们越来越多的研究兴趣。然而，超分子手性对它们的机械和电气性能的影响仍然知之甚少。本文以柠檬烯为手性源，由非手性苯并菲衍生物合成了一系列光学活性超分子凝胶。由于超分子有序堆积，同手性超分子凝胶具有比异手性凝胶更高的机械强度和电导率。详细研究了超分子在同手性和异手性组装体中的堆积对组装体力学和电学性能的影响，这对于合理设计手性π共轭超分子纳米结构在手性光电子学中的应用具有重要的基础价值.
Discotic pi-conjugated supramolecular assemblies, especially with chiral supramolecular nanostructures, have been attracting growing research interest due to their significant optoelectronic properties and the possibilities of their applications in the new generation of organic semiconductors. However, the impact of supramolecular chirality on their mechanical and electrical performances remains poorly understood. Herein, a series of optically active supramolecular gels were formed from achiral triphenylene derivatives by introducing limonene as the chiral source. Owing to the well-ordered supramolecular packing, the homochiral supramolecular gels exhibited greater mechanical strength and higher conductivity, compared to heterochiral architectures. The impact of supramolecular packing in homochiral or heterochiral assemblies on their resulting mechanical and electrical performances was investigated in detail, which might be of great fundamental value for the rational design of chiral pi-conjugated supramolecular nanostructures for applications in chiral optoelectronics.
