Abstract

We synthesized a novel poly (substituted thiophene) which has a long alkyl group with a urethane bond at the 3-position of the thiophene ring. The UV-visible absorption and X-ray diffraction methods reveal thermochromic properties of the polymers, which show the possibility of applying them to reversible thermal recording. The color change of the polymer from brownish-red to yellow was fixed by heating and quenching to room temperature (heat-quenching method). The fixed yellow color returned to the initial color of brownish-red after annealing at 100 °C (annealing method).

      It is know that some neutral poly(3-alkylthiophenes) undergo reversible color changes due to the type of solvent, temperature variation, and hydrostatic pressure [15–20]. The temperature dependence of the absorption spectra of poly(3-alkylthiophenes) is an effect that has attracted the attention of scientists [16,18,21], they have registered an appreciable spectral change when heating the poly(3-alkylthiophenes). The presence at least two phases in the solid state has been observed with a well-defined isosbestic point when the temperature rises from 20 to 150 °C.
