A study on the synthesis and bactericidal activity of certain copolyesters containing bischalcone moiety in the main chain


Four copolyesters were synthesized from 3,3-(1,4-phenylene)bis(1-(4-hydroxyphenyl)prop-2-en-1-one (THAP) and 3,3-(1,4-phenylene)bis(1-(4-hydroxy-3-methoxyphenyl)prop-2-en-1-one (TMAP) by phase transfer catalyzed polycondensation with adipoyl chloride and sebacoyl chloride and a common diol-I 1,5-dihydroxy naphthalene. These copolyesters were characterized by solubility data and viscosity values. The microstructure of the repeating unit was confirmed by IR, 1 H NMR and 13C NMR. These copolyesters displayed potential bactericidal activity against pathogenic bacteria.
