A sequence of two new post-synthetic modifications, epoxidation using dimethyldioxirane and subsequent epoxide ring-opening, was developed, maintaining the MOF network. A kinetic study shows that the functionalization of metal-organic frameworks with synthetically versatile and reactive oxirane groups is even possible for small pore diameters.

A buried polar bilayer interface composed of interdigitated peptide ends and a high density of CF3COO− counterions passifying lysine amines are identified in nanotubes obtained by self‐assembly of short peptides. The structure reveals distinct characteristics that differentiate peptide bilayers and lipid bilayers that can now be exploited for the construction of lipid‐like nanomaterials with protein functionality.

Reactive transport enhancement of CO2 in poly(4-vinylphenolate)s.

In this letter a method is described to synthesize new polysiloxane architectures by photoacid catalysis. An oxasilaspirocycle is designed that is able to undergo a photoacid generator catalyzed ring-opening reaction leading to either a homopolymer or to copolymers with hydroxyl-terminated polydimethylsiloxane. These polymers feature a defined amount of double bonds in the backbone, which is controlled by the ratio of oxasilaspirocycle to the comonomer. The former was prepared by trispentafluorophenylborane-catalyzed intramolecular hydrosilylation of a dialkenyloxysilane with an appropriate structural motif. The UV-initiated polymerization was characterized via in situ IR spectroscopic studies to determine the rate of reaction.

Photoacid-induced siloxane cross-linking of stimuliresponsive copolymer micelles allows the synthesis of well-defined organic−inorganic hybrid nanoparticles. Two conceptually different synthetic approaches are presented, both via photoinduced crosslinking of poly(4-hydroxystyrene-block-styrene) micelles and via one-pot photoacid-catalyzed micelle formation and siloxane cross-linking of poly(4-tert-butoxystyrene-block-styrene). The multistep synthetic route showed intermicellar cross-linking leading to agglomerates. In contrast to this, the formation of the nanoparticles via the one-pot synthesis yielded well-defined structures. The use of different siloxane crosslinking agents and their effects on the properties of the cross-linked micellar structures have been evaluated. Scanning electron microscopy and differential scanning calorimetry indicate rigid core cross-linked nanoparticles. Their size, molar mass, and swelling behavior were analyzed by dynamic and static light scattering. Cyclic siloxane cross-linking agents lead to residual CC double bonds within the nanoparticle core that allow postsynthetic modification by, e.g., thiol−ene click reactions.
