Preparation and evaluation of new heterocyclic compounds based on benzothiophene derivatives as antifouling additives for marine paint

Abstract

IN the present work three synthesized heterocyclic compounds based on benzo[b]thiophen derivatives (I, II and III) were prepared and confirmed by their IR, Mass and NMR spectra and tested for their antimicrobial activity against some representative slime-forming microbiofouling organisms. The synthesized compounds are evaluated according to their biological activity against macrobiofoulants and also as biocides in a special type of tin-free self-polishing paint. The results showed that the biocidal, antimicrobial activity and antifouling activity of the prepared compounds was quite significant and could thus be used as antifouling agents.
