The representative of a new heterocyclic organic compound is reported. This compound, which is related to the 3-(2,3-dihydro-[1,4]diselenino[2,3-c]thiophen-5-yl)-8-(2,3-dihydro-[1,4]diselenino[2,3-c]thiophen-7-yl)-1,10-phenanthroline dmit2 (2-thioxo-1,3-dithiol-4,5-dithiolato) structure, has been prepared chemically and distinguished by using cyclic voltammetry experiments with iR compensation and electronic absorption spectra. This compound has polymerized successfully on the working electrode surface yielding polymer with reasonable band gap and practical stable to the anodic conditions, the scan rate test proves that the polymer is not diffusion limited.
