Reversible Phase Transitions in a Buckybowl Monolayer

摘要

Many chemical compounds exist in more than one crystalline form; however, the reasons for the appearance of different polymorphs during crystallization are still largely unknown. Polymorphism in general, and the inability to control it in particular, have tremendous technological and commercial consequences in fields such as pharmaceutical and materials science. The first observation of a transformation between two different polymorphs of an organic compound dates back to 1832, when Liebig and Wohler reported the conversion of silky needles of benzamide into rhombic crystals.
