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.

Several tens of superlarge hydrothermal gold deposits related to volcano subvolcanic rocks have been defined in the world since 1980s. It is of great importance, both economically and theoretically, to study this type of gold deposits. The newly discovered Jinchang gold deposit, Heilongjiang Province, is one of this type of gold deposits, which is hosted by breccias bodies that are associated with volcano-subvolcanic rocks. More than 30 t Au resource has been proved after preliminary exploration by the 5〓 Geological Party of Gold Headquarter.
