Direct synthesis of CdSe nanoparticles in poly(3-hexylthiophene).
A new approach was developed for the synthesis of nearly monodisperse CdSe nanoparticles directly in a polymer-containing solution in the absence of any other surface capping molecules. The comparatively high synthesis temperature reaction produces good quality crystalline CdSe nanoparticles. Time-resolved microwave conductivity measurements show that photoinduced charge separation occurs at the interface between the CdSe quantum dots and the polymer. This method can be extended to the synthesis of other II-VI semiconductor nanomaterials directly in a polymer-containing solution.
