Abstract
Abstract A set of compounds based on 4-amino-4H-1,2,4-triazole group, namely, 4,4′-(4-amino-4H-1,2,4-triazole-3,5-diyl)dibenzoic acid (1), 4,4′-(4-amino-4H-1,2,4-triazole-3,5-diyl)dianiline (2), 4,4′-(4-amino-4H-1,2,4-triazole-3,5-diyl)diphenol (3), were obtained through reacting different aromatic nitrile and hydrazine under the solvothermal conditions, respectively. The title compounds 1-3 have been characterized by IR, UV–Vis, 1H NMR, 13C NMR, element analysis (EA), single crystal X-ray diffraction, and powder X-ray diffraction (PXRD). In these compounds, a plenty of hydrogen bonds (C/N–H⋯O/N) and C-H∙∙∙π can be obviously obtained, through which a three-dimensional framework will be constructed. The solid-state luminescent spectra of 1-3 show that the emission maxima are observed at 398, 464 and 402 nm, respectively. The order of maximal peaks is 1
