Ring-opening metathesis polymerization was used to modify organic soluble gold nanoparticles with redox-active polymers. A gel-permeation chromatography study revealed that each nanoparticle is modified with approximately 11 polymer chains. Electrochemical studies of nanoparticles modified with block copolymers of two different redox-active groups revealed that each monomer is electrochemically accessible, while no current rectification was observed.

Covalently Linked

A topic of growing importance is the nano-structuring of inorganic materials by exploiting interactions with self assembling polymers. One example are multiphase polymers.Driven by the mixing enthalpy, most polymers phase separate below their critical solution temperature. The components of block copolymers are covalently linked, restricting separation to microscopic length scales. Depending on composition, block copolymers form different equilibrium morphologies representing the energetically most favorable balance between- interfacial area and chain conformation.Mass thickness contrast of polymers is often weak and conventional TEM can thus fail to characterize the morphology unless selective staining methods exist. This is the case for the poly(isoprene)-b-poly(ethyleneoxide) diblock copolymer system (PI-b-PEO) used as a structure directing agent and to provide solubility (see below). Fig. 1 shows the micro-domain morphology of PI-b-PEO where the rubbery phase is selectively stained with OsO4 .Hybrid materials are obtained by addition of an inorganic precursor to a solution of PI-b-PEO in a "mutual" solvent.

End-functionalized poly(3-hexylthiophene) (P3HT) has contributed to continued advancements in conjugated polymer applications, especially within organic electronics. P3HT synthesized using Kumada catalyst-transfer polymerization (KCTP) has many favourable attributes such as controlled molecular weight, high regioregularity, and narrow dispersity. With the addition of reactive end-groups, P3HT plays an important role in advancing the development of hybrid materials and preparation of block copolymers. Exploring methods of end-functionalization that result in heteroatom-bond formation, giving a non-carbon atom bonded to the terminal thiophene, could help control and understand the p–n junction of hybrid materials. This research highlight focuses on the development of a novel and facile way of end-functionalizing P3HT with chalcogens.
