Abstract Two main synthetic strategies are used to prepare conjugated oligomer‐ or polymer‐nanocrystal nanohybrids. In the first strategy ligand exchange is invoked to either replace with a bifunctional ligand, which contains a second functional group for coupling with conjugated oligomers or polymers (COs or CPs), or exchange for the functionalized COs or CPs in a “grafting‐onto” process. Alternatively, in the second strategy the nanocrystal (NC) is passivated with functional ligands from which COs or CPs are directly grown in the absence of ligand exchange. The well‐defined interface between the COs or CPs and NCs facilitates an efficient charge‐transfer between them.
