Organic charge-transfer (CT) complexes are co-crystals composed of electron donor and acceptor molecules, exhibiting distinctive optoelectronic properties. However, due to strong intermolecular aggregation, it is generally difficult to fabricate thin films from CT co-crystals as single-component materials. In this study, we prepared CT–PNC composite films by uniformly dispersing CT complexes in a lead halide perovskite nanocrystal (PNC) matrix. Optical characterization of the resulting composite films revealed photoluminescence quenching and shortened exciton lifetimes of the PNCs, suggesting the occurrence of energy and/or charge transfer processes.
