▎ 摘  要

A covalently cross-linked graphene oxide (GO) catalyst was prepared by a cross-linking process using nucleophilic reaction of copper(II)-coordinated 5,10,15,20-tetrakis(aminophenyl)porphyrin (CuPPh) with carboxyl groups at the edges of GO (GO-CuPPh). The structure of the catalyst was characterized using different techniques such as Fourier-transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS), thermogravimetric analysis (TGA), and inductively coupled plasma (ICP) spectroscopy. All analyses confirmed successful covalent immobilization of CuPPh on GO. The activity of the catalyst was then studied for synthesis of 1,4-disubstituted 1,2,3-triazoles derivatives by reaction of various aryl azides and different terminal alkynes in mild reaction condition with good to excellent yield.
