Benzenetricarboxamide-cored triphenylamine dendrimer: nanoparticle film formation by an electrochemical method
2013
By dropwise addition of a solution of tricarboxamide-cored triphenylamine dendrimer G1 in THF into water (5 × 10−6 M), nanoparticles with average diameters of 80 ± 20 nm were formed and collected by centrifugation. The particles show aggregation induced emission and emit green light under photoluminescence conditions. The particles can be fused together by applying a concept of electrochemical curing; the G1 particles are coupled through electrochemical oxidation to form a film. This method provides a fast assembling process for constructing films in a few seconds. Fabrication of electrochromic and fluorescence switching devices was demonstrated.
