Pyridine is relatively electro deficient due to the electronegative nitrogen in the aromatic ring. It have many advantages which are strong electron withdrawing properties, high hole mobility and quantum efficiency in organic electronics. Due to the electron-deficient nature of pyridine, pyridine-based conjugated polymers show n-doping properties, offering a possible utilization of pyridine-based conducting polymers as anode battery materials. Reversible electrochemically driven n-doping behavior of polypyridine derivatives, is accompanied by a color change from blue (reductive) to yellow (neutral). The effect is halochromism of the pyridine polymer films. In the study, the synthesized polymer also has a halochromism using a Lewis acid (HCl, BF3) and defunctionalization using a base (Et3N). In order to prove the effects in organic electronics, we also fabricated the devices based on these polymer with phenyl-C71-butyric acid methyl ester (PC71BM) and ITIC for organic photovoltaics. |
