Abstract

We discuss a model of the origin of the thermochromism in the poly(3-alkylthiophene)s, in which the thermochromism results as a consequence of thermally generated rotational defects in the geometric order of the polymer chains. These rotational defects lead to changes in the electronic structure and the corresponding optical properties of the polymer. The consequences of the model have been verified by photoelectron spectroscopy.
