Conjugated polymer nanoparticles (CPNs) are attracting considerable interest in a wide variety of applications such as biological labels, chemical sensors, and optoelectronic devices. Here, we demonstrated the preparation of white-emissive conjugated polymer nanoparticles wrapped with graphene oxide (GO) nanosheets. Highly stable, GO wrapped, poly(9,9-di-n-octylfluorenyl-2,7-diyl) nanoparticles (GO-PFO NPs) were successfully obtained by utilizing the GO nanosheets as an interface stabilizer in an emulsification process. The key finding of this work is that the synthesized GO-PFO NPs exhibited unique white-emitting photoluminescence with a characteristic green-emissive broad band even though PFO is representative blue-emissive polymer. In this presentation, systematic studies on what the origin of the color conversion in GO-PFO NPs is will be discussed. |
