The research in this Paper is focused on creating organic materials that can match the inorganic semiconductors in terms of performance and stability. A new thiophene derivatives -2-(2.3-dihydro-7-(2,3-dihydro-[1,4]diselenino[2,3-c]thiophen-7-yl)-[1,4]diselenino[2,3-c] thiophene-5-carboxamido)-4-methylpentanoic acid have been characterized by absorption spectroscopy and cyclic voltammetry. The processes were made with H2O and sodium phosphate (Na3PO4) as supporting electrolyte), at scan rate of 0.1 Vs−1 on a glassy carbon working electrode Ag wire reference electrode and Pt counter electrode. The absorption maximum for the monomer was appeared two peaks at 265 and 345 nm, which corresponds to a π-π* transition from the conjugated material, the monomer was grown successfully on the electrode surface throughout repetitive cycling and shown polymer has ( λmax ) peak at 690nm indicative the extension of conjugated chain length in the polymer than the monomer.
