Azobenzene functionalized polyelectrolytes and polyamphiphiles are novel functional polymers with many interesting characteristics such as the photo-responsive properties based on the photo-induced cis-trans isomerization, the ability to build up ordered supramolecular structure, and the sensitivity to the environmental stimuli. The aim of this dissertation is to investigate the rules that control the formation of ordered structures from the azo polyelectrolytes and polyamphiphiles based on the supramolecular interaction, to explore the relationships between the material functionality and the supramolecular self-assembled structures at different levels, and to establish the methods for producing novel materials with potential applications in photonic and electronic areas.
