机械致变色发光（ML）材料的发射波长在固态时因分子堆积而不同，而当分散在溶剂中时，它们表现出一个均匀的发射波长。使用自上而下的方法，我们开发了一种方法，可以保持在水溶液中的ML材料的固态特性。我们证实，在固态的机械致变色发光的四苯乙烯衍生物的晶体学信息被保存在水溶液中，通过与多糖络合。配合物的水溶液在1周以上是稳定的。
The emission wavelengths of mechanochromic luminescent (ML) materials differ in the solid state based on molecular packing, whereas they exhibit one homogenized emission wavelength when dispersed in a solvent. Using a top-down approach, we developed a method that can maintain the solid state properties of ML materials in aqueous solutions. We confirmed that the crystallographic information on a tetraphenylethylene derivative with mechanochromic luminescence in the solid state was preserved in aqueous solutions via complexation with polysaccharides. The aqueous solutions of the complexes were stable for over 1 week.
