Dynamic Interfacial Adhesion through Cucurbit[n]uril Molecular Recognition.
Angewandte Chemie, 2018 Supramolecular building blocks, such as cucurbit[n]uril (CB[n])-based host-guest complexes, have been extensively studied at the nano- and microscale as adhesion promoters.

Photoredox cooperative N-heterocyclic carbene/palladium-catalysed alkylacylation of alkenes
Nature Communications, 2022 Three-component carboacylation of simple alkenes often requires directing groups and strained substrates. Here, the authors report a photoredox N-heteroyclic carbene/Pd-catalysed alkylacylation of alkenes with aldehydes and unactivated alkyl halides ...

Molecular recognition of the nucleosomal “supergroove” [PDF]
Proceedings of the National Academy of Sciences, 2004 Chromatin is the physiological substrate in all processes involving eukaryotic DNA. By organizing 147 base pairs of DNA into two tight superhelical coils, the nucleosome generates an architecture where DNA regions that are 80 base pairs apart on linear DNA are brought into close proximity, resulting in the formation of DNA “supergrooves ...

Measuring Entropy in Molecular Recognition by Proteins.
Annual Review of Biophysics, 2018 Molecular recognition by proteins is fundamental to the molecular basis of biology. Dissection of the thermodynamic landscape governing protein-ligand interactions has proven difficult because determination of various entropic contributions is quite ...

Molecular Recognition in a Thermoplastic Elastomer
Journal of the American Chemical Society, 2005 Selective incorporation of bisurea guests in thermoplastic elastomers with poly(tetrahydrofuran) soft blocks and bisurea containing hard blocks is observed when the distances between the urea groups of host and guest match. The incorporation leads to significant modulation of mechanical properties.
