To combine several inorganic components with organic material in a controlled special and permanent manner still remains a difficult issue. Two specifically functionalized block copolymers were synthesized sep. and combined in a second step. A heterofunctional poly(ethylene glycol) (PEG) block copolymer bearing a single amino unit, a short PEG spacer, and multiple catechol functionalities was obtained via anionic ring-opening polymerization (AROP). Using the reversible addition-fragmentation chain transfer (RAFT) radical polymerization technique, a semiconducting block copolymer with carbazole side groups was obtained. The second polyacrylate block contained reactive ester groups and was polymerized onto this hole conducting block. By substitution of the reactive esters with the amino functional PEG-catechol block copolymer and cysteamine Me disulfide, a hole conducting polymer material with two orthogonal anchor groups for the coating of CdSe QDs, and also for TiO2, was obtained. TEM images show that upon coating of both materials we were able to obtain QDs homogeneously distributed at the surface of TiO2 nanoparticles. This spatial assembly is a consequence of the special directing features of the copolymer, possessing two orthogonal anchor groups combined in one material.
