POLY 82 |
| High-molecular-weight conjugated polymer nanoparticles with average particle sizes of around 30 nm and molecular weights of up to Mn = 4.1 x 104 g mol-1 have been prepared for the first time in aqueous emulsion. For this step growth polymerization the Glaser coupling was used as a high yield reaction. A key to conducting such reactions in aqueous emulsion was found to be the utilization of the lipophilic bidentate ligand dinonylbipyridine in the copper(I/II) catalyst employed. A copolymerizable diethynyl substituted perylenediimide derivative was synthesized and incorporated covalently into the conjugated polymers. An effective energy transfer to incorporated dye occurs in the poly(aryl diethynyl) nanoparticles prepared. |
