Reactive Polymers: A Versatile Toolbox for the Immobilization of Functional Molecules on TiO₂ Nanoparticles

Abstract

Three in one: TiO2 nanoparticles have been functionalized with reactive polymeric ligands that incorporate chelating dopamine anchor groups, a modifying unit to allow the binding of functional molecules such as fluorescent dyes (see picture), as well as groups to tailor the solubility of the inorganic nanocrystals in different solvents.

Liquid Crystalline Orientation of Semiconducting Nanorods in a Semiconducting Matrix

“…The reactive ester groups of this monomer are known to react with any primary amine. [16] At least the polymer to ) belonging to the pentaflouroacrylate disappears after stirring the dissolved polymer with an excess of the amine containing anchor group. After conversion an absorption at 1 647 cm À1 can be detected showing the formation of an amide bond.…”

Influence of Binding‐Site Density in Wet Bioadhesion

“…Synthesis of Poly(pentafluoro-phenylacrylate) (PFA): PFA was prepared as reported previously [13]. Gel permeation chromatography analysis (tetrahydrofuran, light scattering detection) gave a numberaverage molar mass of M n ¼ 29.…”

“…We synthesized a statistical copolymer whose structure and functionality can be tailored. [13] The copolymer contains amino-terminated side groups and catechol groups. The catechol groups are capable of binding to minerals, metals, and metal oxides.…”

Liquid Crystalline Ordering and Charge Transport in Semiconducting Materials

“…The block-copolymers needed for the surface modification are prepared mostly by RAFT polymerization [129] via a reactive ester intermediate. [130] The reactive ester allows the incorporation of various anchor groups, [125,130] which permit a coating of oxidic as well as sulfidic nanostructures (see Figure 18). [125,128c] The concept of solubilizing inorganic nanorods can be extended to nanorods made from ZnO, W. Pisula, M. Zorn, J. Y. Chang, K. Müllen, R. Zentel Figure 17.…”
