摘要：

Aiming at the preparation of nanometer-size polydiacetylene microcrystals, the crystallization process during reprecipitation method was investigated using electron micrographs and light-scattering technique, Mt found that an amorphous nanoparticle was formed initially and subsequently crystallized, We conclude that amorphous nanoparticles must be sufficiently small in order to achieve nanometer-size crystals.
