optically isotropic mesophase composed of a conglomerate of macroscopic chiral domains with opposite sense of chirality even though the constituent molecules are achiral. This mesophase was proposed to result from the helical packing of hydrogen‐bonded triazine aggregates, providing long‐range chirality synchronization. The results provide first evidence for macroscopic achiral symmetry breaking upon conglomerate
带有单个寡聚(环氧乙烷)(EO)链的2,4-二氨基-6-苯基-1,3,5-三嗪形成光学各向同性的中间相,该中间相由宏观手性域的聚集体组成,尽管手性相反组成分子是非手性的。提出该中间相是由氢键合的三嗪聚集体的螺旋堆积产生的,提供了远距离手性同步。研究结果为宏观的非手性对称性破裂提供了初步证据,该非对称性各向异性是由与益生元分子有关的简单N杂环的氢键结合体形成的无定形各向同性相中的团聚体破裂。
