  • Abstract In this study, we prepared PS-derivatives (PVB-DAP) through NMP polymerization and the post-functionalization of H-bonding moieties be proceeded via “click chemistry”. FT-IR, 1H NMR, 13C NMR confirmed the chemical structure of PVB-DAP and Azo-T. The supramolecular complexes through Hetero-complementary hydrogen bonding between Diamidopyridine and Thymine were investigated. We demonstrate thermal stability of small molecules which has hydrogen bonding by DSC and TGA, respectively. Due to the unique photoresponsive of azobenzene materials after exposed UV lamp (365 nm), so the conformation of azobenzene will be changed because the dipole moment of trans and cis is difference. Surface contact angle (CA) of supramolecular films decreased after UV and back to its original state after exposure to visible light. The reversibility was also observed through physical crosslinking network and dipole moment change. Previous studies indicate that azobenzene can be applied to optical storage and memory. We performed OM and AFM to investigate the surface relief gratings through hydrogen-bond supramolecular film. We prepared novel supramolecular materials that possess photo-tunable and thermal conformity through Hetero-Complementary hydrogen bonding.
