Abstract: Surface and interfacial reactions involving functional polymers with metals and inorganic semiconductors were studied. GaAs-PMMA hybrids and ZnO-PMMA core-shell hybrid nanoparticles were prepared via surface-initiated atom transfer radical polymerization (ATRP) from the GaAs and ZnO surfaces. The chemical states and physical properties of surfaces and interfaces of the hybrids were investigated. Self-assembled monolayers (SAMs) of ZnO quantum dots (QDs) were deposited on GaAs substrates via bifunctional molecules, which acted as a coupling agent for ZnO QDs and passivated the GaAs surfaces. In addition, the chemical states and electronic properties of the interface between aluminium and a conjugated copolymer of hexylflurene and benzoate containing chelated Eu complexes (PF6-Eu(dbm)2phen) were studied in situ by XPS and UPS.
