PYRIDINE BASED POLYMERS. SYNTHESIS AND CHARACTERIZATION

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.
