The new thiazole-based polymer was synthesized by the Suzuki-Miyaura crossing-coupling reaction of 5-bromo-N-(3-bromophenyl)thiazol-2-amine and 9,9-dioctyl-9H-fluorene-2,7-diboronic acid bis(pinacol) ester. The synthesized monomer and poly[N,N'(1,3-phenylene)bis(thiazol-2-amine)-co9,9’dioctylfluorene] (Poly[Tm]) were characterized by the Elemental analysis, Fourier Transform Infrared spectroscopy, Nuclear Magnetic Resonance spectroscopy, Thermogravimetric analysis and Gel Permission chromatography. Furthermore, the optical properties of the Poly[Tm] were studied at three concentrations of 0.625, 1.25 and 2.5 mM in solution. The absorption band edge values of Poly[Tm] decreased with the increasing concentration of the solutions. When the concentration of the Poly[Tm] solution was increased, transmittance values of the Poly[Tm] were increased, and its molar extinction coefficient was resulted in higher absorbance values. Synthesized Poly[Tm] could provide a novel concept for the design of transistors and photovoltaics.
