A new antibacterial material has been elaborated by grafting mesoarylporphyrin on cotton fabric by the means of cellulose azidation followed by Click-Chemistry reaction with acetylenic porphyrin. Azidation and functionalization have been checked by ATR-FTIR spectroscopy. Under irradiation with visible light, this material displayed an antibacterial activity against representative strains of Escherichia coli and Staphylococcus aureus. This new photobactericidal textile has potential for industrial, medical, and household applications. (C) 2009 Elsevier B.V. All rights reserved.
