Abstract

Chirality at a supramolecular level is currently attracting great attention attributed to rapid developments in supramolecular chemistry. Herein, we report a new type of chiral self-assembly based on the cyanine dye MTC. The chiral H-aggregates of MTC could form spontaneously from achiral J-aggregates, and could return back to achiral J-aggregates in high concentration on increasing the solution temperature.

摘要

由于超分子化学的迅速发展，超分子水平上的手性目前正备受关注。在此，我们报道了一种基于花菁染料MTC的新型手性自组装。MTC的手性H聚集体可由非手性的J聚集体自发形成，并且在升高溶液温度时，高浓度下可变回非手性的J聚集体。
