A light-assisted RAFT copolymerization protocol is established and investigated for the synthesis of 2-hydroxyethyl acrylate (HEA) / spiropyran acrylate (SPA) copolymers with enhanced SPA-contents. Radiation with visible light prevents the spiropyran (SP) motif from isomerizing into the open merocyanine (MC) form which can interfere with the polymerization process by abstracting a hydrogen atom from an active radical via its phenolic oxygen.

Surface-initiated photoinduced electron transfer-reversible addition-fragmentation chain transfer (SI-PET-RAFT) provides a light-dependent tool to synthesize polymer brushes on different surfaces that tolerates oxygen and water, and does not require a metal catalyst. Here we introduce improved control over SI-PET-RAFT polymerizations continuous flow conditions. We confirm the composition and topological structure of the brushes by X-ray photoelectron spectroscopy, ellipsometry, and AFM.

The visual photopigment rhodopsin (Rh) is a prototypical G protein-coupled receptor (GPCR) responsible for initiation of the phototransduction cascade in rod photoreceptors. Similar to other GPCRs, Rh can form dimers or even higher oligomers and tends to have a supramolecular organization that is likely important in the dim light response. Rh also exhibits high affinity for lipid rafts ( raftophilicity) upon light-dependent binding with the cognate G protein transducin (G), suggesting the presence of lipid raft-like domains in the retinal disk membrane and their importance in phototransduction.
