Giant domain formation in a thin film of bisstyrylanthracene derivatives by a simple melt process

Bisstyrylanthracene derivatives with long alkyl side chains (BSA), which were prepared into the thin films composed of giant anisotropic domains by simple melt process, showed interesting property. The derivatives that changed the chains length and chains form were synthesized. We introduced the film preparation and investigated thermal properties of the films using differential scanning calorimetry (DSC), polarization micrograph, and fourier transform infrared spectroscopy (FT-IR). The phenomena of the giant domain formation and phase transition in USA films are discussed.
