Abstract

A flexible and transparent anti-bacterial film is prepared by depositing polyterthiophene incorporating porphyrin onto the poly(ethylene terephthalate) sheet by a simple and rapid oxidation polymerization method. The film can generate singlet oxygen by FRET from polyterthiophene to porphyrin to effectively kill the adsorbed bacteria under white light.

Keywords: E. coli; antibacterial activity; conjugated polymers; films; porphyrin.
