Photoinduced hole transfer forming polymer quantum dot nanocomposites

摘要

The study of hole transfer from CdSe QD core to ligands under visible light irradiation and conductive polymer-QD composites formation without conventional photoinitiator.rnConductive polymers have been widely used in electronic and optical devices because of their easy solution processing and mechanical flexibility. Quantum dots (QDs) with properties between bulk semiconductors and discrete molecules have been widely studied. Conductive polymer-QD organic-inorganic hybrid composites with dual properties, those of the polymer and of the QD, have attracted significant attention due to their potential applications in photovoltaic cells, LEDs and bio-sensors. Because interfaces between polymer and QDs have substantial effect on the electronic interaction, and QD aggregation poses a major problem in preparations of composite materials, physical blending of the components does not produce products with the desired properties.
