Beschreibung
Zusammenfassung:	The invention provides a silsesquioxane-based fluorescent porous hybrid polymer with a D-A structure as well as preparation and application of the silsesquioxane-based fluorescent porous hybrid polymer in gold recovery. A conjugated organic fluorescent monomer with a D-A structure is innovatively prepared by taking polyhedral oligomeric silsesquioxane as a construction unit, and the conjugated organic fluorescent monomer and the polyhedral oligomeric silsesquioxane are cross-linked through a Heck reaction to prepare the fluorescent porous hybrid polymer (PTSC) with the D-A structure. The polymer has the advantages of large specific surface area, strong light absorption capability, narrow optical band gap and excellent semiconductor behavior. When the Au (III) adsorbent is used as the Au (III) adsorbent, adsorption and photocatalytic reduction are carried out at the same time under irradiation of visible light, the adsorption performance is excellent, the adsorption efficiency within 15 min can reach about 80%
