A series of 2, 3, 5, 6-tetra-substituted pyrrolo [3, 4-c] pyrrole-1, 4 (2H, 5H)-dione (DPP) derivatives carrying thienyl-, 3, 4-ethylenedioxy-thienyl-(EDOT-) and 3, 4- ethylenedithiathienyl-(EDTT-) substituent groups have been synthesized and electrochemically polymerized. The polymers were investigated using UV/vis absorption spectroscopy and cyclic voltammetry. It was found that the growth of the polymers ...
