The photoinduced energy transfer process from conjugated polymer (PPE4+) to CdTe nanocrystals was found both in solutions and in thin films by a fluorescence spectroscopic technique. Films of PPE4+ blended with CdTe‐2 nanocrystals were formed by an electrostatic layer‐by‐layer assembly technique. Light emitting diodes were fabricated using CdTe‐2 as an emitter in PPE4+ host. PPE4+ works as a molecular wire in the energy transfer process from the polymer to the CdTe‐2 nanocrystals.
