Functionalized hyperbranched polymers via olefin metathesis [PDF]
, 2009 Hyperbranched polymers are highly branched, three-dimensional macromolecules which are closely related to dendrimers and are typically prepared via a one-pot polycondensation of AB_(n≥2) monomers.^1 Although hyperbranched macromolecules lack the ...

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Advanced Porous Materials for Maritime Carbon Capture
Advanced Materials, EarlyView.Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

The effect of host structure on the selectivity and mechanism of supramolecular catalysis of Prins cyclizations. [PDF]
, 2015 The effect of host structure on the selectivity and mechanism of intramolecular Prins reactions is evaluated using K12Ga4L6 tetrahedral catalysts. The host structure was varied by modifying the structure of the chelating moieties and the size of the ...

Advanced Materials, EarlyView.The selective hydrogenation of acetylene over laterally condensed Pd and Pd–Au catalysts (LCCs) was investigated using operando X‐ray absorption and photoelectron spectroscopy in combination with density functional theory. Pd‐LCCs were found to incorporate significantly more carbon into the metal lattice than Pd–Au LCCs, where the carbon uptake governs

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]
, 2016 The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the
