Conjugated polymer nanoparticles (CPNs) have received considerable attention over the last decade in an effort to realize brighter luminescence, facile processing, and enhanced device efficiency. This talk presents a new methodology to prepare CPNs using phase separation in films of phospholipids and conjugated polymers. The films contain nanoassemblies because of a difference in physicochemical properties between hydrophobic polymers and polar lipid heads together with the comparable polymer side chain lengths to lipid tail lengths, thus producing CPNs upon disassembly in aqueous media by the penetration of water into polar region of lipid heads. The molecular origin of the bathochromic shift in the absorption spectrum of CPNs investigated using density functional theory calculations will be presented together with addressing the hybridization of CPNs and magnetic nanoparticles for simultaenously carrying out diagonosis by magnetic resonance imaging and photothermal therapy. |
