Abstract

The fabrication and characterization of a hybrid polymer p-n junction-type thin film via electropolymerization of NPs and a precursor polymer is described. Blends of TiO ₂ NPs, CdSe NCs, Cbz-COOH, and PVK were utilized to enable electrochemical deposition on ITO glass substrates. Spectroscopic, microscopic, and wetting measurements confirmed thin film fabrication. CV yielded a CPN nanocomposite with electropolymerized (i.e., crosslinked) carbazole units embedding CdSe NCs. Absorption and emission measurements confirmed a charge transfer mechanism between the crosslinked carbazole and the NCs resulting in a p-n junction-type thin film on ITO; with the observed quenching of CdSe NC emission. Several possible applications of such thin films are also discussed.
