Abstract

Inorganic Anions Regulate the Phase Transition in Two Organic Cation Salts Containing [(4-Nitroanilinium)(18-crown-6)]+ Supramolecules

Highlights

From both theoretical and applied viewpoints, phase-transition compounds are popular and valuable in increasing the general understanding of structure–property relations and exploring functional materials with novel physical properties [1,2,3,4,5,6,7,8,9,10]
The The crystal structure ofof1 1was at different differenttemperatures temperatures by X-ray diffraction to crystal structure wascharacterized characterized at by X-ray diffraction to confirm whether the phase transition was associated with structural changes
Two inorganic–organic hybrid crystals based on the [(4-HNA)(18-crown-6)]+ supramolecular cation were reported in this study

Summary

Introduction

From both theoretical and applied viewpoints, phase-transition compounds are popular and valuable in increasing the general understanding of structure–property relations and exploring functional materials with novel physical properties [1,2,3,4,5,6,7,8,9,10]. Phase-transition crystalline materials are usually accompanied by an abrupt change in some physical properties around the transition temperature. These materials show great applications in molecular sensors, switches, and data storage devices [11,12,13,14,15]. Designing special inorganic-organic hybrid compounds with molecular dielectrics is an effective method for synthesizing ideal phase-transition materials [16,17,18,19]. The driving force of these phase-transition compounds can be ascribed to the motional changes in the R–NH3 + guest cation (R = aryl group) or/and anionic units.
