calculations further support these findings, indicating that temperature-dependent intermolecular interactions and conformational changes play a significant role in shaping the optical behavior of the films. These results provide new insights into the structure–property relationships underlying thermochromism
in azopolymer thin films and offer valuable guidelines for the design of thermally responsive photonic materials.

synthesis, electrical and mechanical properties, thermochromism, solvatochromism, and crystal structure [75][76][77][78], have been extensively studied. Their optical properties, conductivity, and field-effect mobility (FEM) strongly depend on chain conformation and the solid-state-packing mode. For example
structure (Figure 20). Nanofiber formation is always accompanied by a color change from orange to dark red, which is referred to as thermochromism [83].
