By changing the position of the homochiral alkoxy substituents of C3-symmetric 1,3,5-trialkynylbenzenes from the center to the periphery, the macroscopic chirality of the resulting aggregates (crystals or fibers), studied by various spectroscopic and microscopic techniques, was inverted, as confirmed by single-crystal X-ray diffraction analysis.
通过将 C3 对称 1,3,5-三炔基苯的同手性烷氧基取代基的位置从中心改变到外围,通过各种光谱和显微镜技术研究的所得聚集体(晶体或纤维)的宏观手性被反转,通过单晶 X 射线衍射分析证实。
