In the recently, conjugated polymers have many possibilities containing thieno thiophene. Such as this polymer has a significantly improved compared with the other polymers characterization. We designed and synthesized a polymer containing thieno thiophene (CNTT) and CN group by well known stille coupling reaction. The physical and optical properties of CNTT were characterized using various studies such as cyclic voltammetry (CV), UV-visible absorption and NMR, and the results will be presented in detail. The high thermal stability of CNTT was determined by thermogravimetric analysis(TGA) and differential scanning calorimeter (DSC) studies. This polymer has electrochemical band gaps of 2.07eV. The HOMO and LUMO energy levels are localized at -5.37 eV and -3.3 eV, respectively. The optical properties were investigated by UV-visible absorption bands in solution and in the solid state around 363nm, 480nm, 774nm. Film absorption state around 382nm, 493nm, 731nm. |
