Abstract

This study describes the synthesis, spectroscopy and band gap energy of a new poly(triphenylamine-thiazolo[5,4-d]thiazole) (p-TPTT) dye. The p-TPTT polymer was examined by GPC, 1H-NMR, FT-IR, UV-vis., fluorescence, thermal analysis (TA) and cyclic voltammetry (CV). It was found that the p-TPTT has a weigh average molecular weight (Mw) of 3596 and it has good solubility in many organic solvents. The TA results showed that the p-TPTT is a stable polymer up to 400-500 [degree]C. The EOptg of the polymer was found to be 1.85 eV in DMSO and 1.55 eV in the solid phase. From the CV measurements, the HOMO and L
