Resumo

PARDO, M. A. et al. PYRIDINE BASED POLYMERS: SYNTHESIS AND CHARACTERIZATION. J. Chil. Chem. Soc. [online]. 2014, vol.59, n.2, pp.2464-2467. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072014000200014.

Two new conjugated polymers, poly(2,3-di(thiophen-2-yl)pyrido[2,3-b]pyrazine) and poly(2,3-di(thiophen-2-yl)pyrido[3,4-b]pyrazine), based on thiophene and pyridine rings were chemically and electrochemically synthesized and characterized by IR, UV-Vis and elemental analysis. Monomers were chemically synthesized at high yield percentages and characterized by FTIR and NMR. Polymers showed p- and n-type doping as well as low bandgap, making them potential candidates for the development of electronic devices.

Palavras-chave : 2,3-di(thiophen-2-yl)pyrido[2,3-b]pyrazine; 2,3-di(thiophen-2-yl)pyrido[3,4-b]pyrazine; poly(2,3-di(thiophen-2-yl)pyrido[2,3-b]pyrazine); poly(2,3-di(thiophen-2-yl)pyrido[3,4-b]pyrazine).
