Abstract
Conjugated polymer nanoparticles have been regarded as promising fluorescent materials for biological application, due to their high emission efficiency, good photostability and low cytotoxicity. In this contribution, we synthesized a conjugated polymer which integrates blue-, green- and red-emitting components into the backbone in an appropriate molar ratio. After being transferred from solution to nanoparticles, its fluorescence color turns from blue to pink with enhanced fluorescence quantum yield. After incorporation of an amphiphilic polymer as matrix, white-emissive polymer nanoparticles are obtained as a result of optimized energy transfer degree among the three components. Finally, their good performance on cell imaging are demonstrated by incubation with HeLa cells, after being proved to be safe for biological application.
