Abstract

Abstract : By meniscus‐dragging deposition in a layer‐by‐layer manner, conjugated polymer nanoparticles with surface bromides are conjugated with amine‐functionalized dendrimers to build up nanocomposite thin films. Abstract : A conjugated polymer, poly(9, 9‐bis(6‐bromohexyl)‐9 H ‐fluorene‐alt‐1, 4‐phenylene), is synthesized, converted to nanoparticles via a nanoprecipitation process, and utilized to fabricate thin films including conjugated polymer nanoparticles. The nanoparticles with surface bromides can be conjugated with an amine‐functionalized dendrimer via a nucleophilic coupling reaction. Thus, when microliter solutions of the particulates are dragged at a constant velocity on substrates alternately in a layer‐by‐layer manner, thin films composed of the nanoparticles and dendrimers can be successfully built up on the substrates. Our results suggest a methodology to control the deposition of thin films bearing conjugated polymer nanoparticles while minimizing processing time and decreasing material consumption.
