Resumen:
Heterocyclic compounds are well known for their biological activity and coordination properties. Some heterocyclic compoundshave been employed in the stabilization against coalescence of metallic nanoparticles in colloidal solutions, for example, tetrazole,triazole, and pyrazole. The aim of this work is to design new polyelectrolytes with heterocyclic pendant groups useful as reducing agentsof Au3+ and as stabilizing agents for the synthesis of colloidal Au nanoparticles. Thus, polyelectrolytes with thiosemicarbazone and1,3,4-thiadiazole pendant groups were used as reducing agents of Au3+ ions and stabilizing agents of Au nanoparticles. The voltammetrystudy of the polyelectrolytes showed that one with thiosemicarbazone pendant groups is the better reducing agent than polyelectrolyteswith heterocyclic pendant groups. The polyelectrolytes can control the growth of the nanoparticles, obtaining structures with an averagesize of 9 nm. In this study, it was concluded that the nature of the heterocyclic group does not have an effect on the shape of nanoparticlesand quasi-spherical nanoparticles were obtained with all polyelectrolytes.
