Facilely controlling the Förster energy transfer efficiency of dendron encapsulated conjugated organic molecular wire–CdSe quantum dot nanostructures

Abstract

Novel dendron encapsulated conjugated organic molecular wire (Den-OPE)–CdSe quantum dot (QD) nanostructures have been designed. By tailoring the size of dendrimers, different amounts of Den-OPEs could be attached to CdSe, which forms different sizes of core–shell Den-OPE–CdSe composites. With an increase in the size of dendrimers, the emission intensity of CdSe QDs increased due to the higher Förster energy transfer (FRET) efficiency from the bigger size Den-OPEs to CdSe QDs.
