(AEDPH3)·(8-OQH)·(H2O): a yellow supramolecular plaster with ammonia adsorption and ammonia-induced discoloration properties

Abstract

A novel supramolecular plaster, namely (AEDPH₃)·(8-OQH)·(H₂O) (1), is synthesized and characterized. This plaster is an organic acid–base compound, which shows a three-dimensional (3D) sandwich-type supramolecular network. It is a yellow gelling material with excellent mechanical properties superior to that of gypsum plaster. Moreover, the plaster can adsorb ammonia (NH₃) effectively, and exhibits an interesting ammonia-induced discoloration property.
