(AEDPH₃)·(ureaH)·(H₂O): A Novel Organic Supramolecular Plaster with Gas Adsorption Performance

A novel supramolecular plaster, namely (AEDPH₃)·(ureaH)·(H₂O) (1), is synthesized and characterized by infrared spectrum (IR), thermogravimetric analysis (TGA), elemental analysis (EA), single-crystal X-ray diffraction (SCD), and powder X-ray diffraction (PXRD). The supramolecular plaster is an organic acid−base compound that shows a 3D hydrogen-bonded supramolecular network with extended 1D channels. It is simple to synthesize and process and shows good mechanical properties similar to the gypsum-based plaster. Moreover, it has nice gas adsorption performance.
