Synthesis and characterization of a series of new emissive flexible copolymers composed of two kinds of special side‐chain functional groups is demonstrated. One of the side‐chain groups provides emissive properties, while the other serves as the ligand unit. The copolymers are used to prepare a new kind of CdTe nanocrystal‐based semiconductor nanocomposite. Their structures and morphologies are characterized and their optoelectronic properties are studied. The results reveal that an energy‐transfer process from the emissive random copolymers to the CdTe nanocrystals occurs, while a photoinduced charge transfer is estimated to be thermodynamically forbidden.
