Synthesis, Characterization, and Antibacterial Activities of a New Lignocellulosic Material Carrying Aryl Triazole Moiety

Contamination of surfaces by bacteria and the emergence of antimicrobial resistant strains are very worrying issues. One of ways to limit the bacterial proliferation is to develop antimicrobial materials. We reported herein the development of new antimicrobial support by grafting different aryl azide onto propargylated Kraft Pulp, using the copper (I)–catalyzed alkyne‐azide 1,3‐dipolar cycloaddition (CuAAC) reaction, forming 1,2,3‐triazole aryl. These novel materials have been investigated for their antibacterial properties against Escherichia coli and Staphylococcus aureus. The developed materials acquire its antimicrobial potential only after grafting via triazole link. Depending on the substituent of the grafted aryl, the elaborated materials showed a bacteriostatic or even bactericidal activity.
