▎ 摘　　要

A number of bioactive azo dyes based on xanthene moiety were synthesized through an eco-friendly route using CuI-graphene nanocomposite as a sustainable reusable catalyst in ethanol aqueous solution at room temperature. The procedure involved the reaction of 3,4-(methylenedioxy)aniline with pre-synthesized (E)-1,2-diphenyl-1-diazene in 2: 1 molar ratio. The use of water as a green and nonvolatile solvent, energy-saving, and high yields of products within a short reaction time increase the economic and environmental superiority of the current protocol. Some of the synthesized compounds were screened for their antioxidant and antibacterial activities. Good results were obtained in both cases of antioxidant and antibacterial activities.
