Revealing the order-disorder type phase transition mechanism in two new supramolecular clathrates

Phase transition materials can be applied for energy storage or environmental temperature control due to their characteristic of releasing or absorbing a large amount of heat near phase transition temperature. Herein, two new supramolecular-based compounds [(NRT)-(18-crown-6)][ClO4] and [(NRT)-(18-crown-6)][BF4] (1 and 2) have been constructed and their phase transitions were systematically characterized by DSC, variable temperature single-crystal/powder X-ray analysis and Raman spectroscopy.
