Water Accessibility to the Binding Cleft as a Major Switching Factor from Entropy-Driven to Enthalpy-Driven Binding of an Alkyl Group by Synthetic Receptors
drove the binding of the alkylgroup with the enthalpic driving force being dominant. The binding site of the four‐pillared receptor (1) is open and accessible to water molecules, and is more hydrophilic than that of the eight‐pillared receptor (4). We propose that the alkyl chains of 1 are exposed to water to produce a room to accommodate the guest to result in enthalpy‐driven hydrophobic binding, whereas

Mucoadhesion and mucus-sensitive materials have many applications. Redundant chain-ends within branched polymer emulsifiers have been functionalized with thiols, without compromising emulsion stability, to create mucus-interacting emulsions.

The present invention provides turn-ON dioxetane-based chemiluminescence probes based on the Schapp's adamantylidene-dioxetane probe, which are capable of detecting or imaging, more specifically, determining the presence, or measuring the level, of proteases, as well as compositions and uses thereof.

demonstrated to be used as an efficient supramolecular reactor for the room temperature Suzuki cross-coupling reaction of a wide range of aryl halides, including even aryl chlorides with phenylboronic acids in aqueous environment. These results demonstrate that self-assembly of amphiphilic rod-coilmolecules can provide a useful strategy to construct an efficient supramolecular reactor for aromatic coupling
Carboxylic acids 1a and 1b bearing three poly(ethylene glycol) (PEG) chains and carboxylic acid 1c bearing one PEG chain were designed and synthesized. The carboxylic acids 1a–c were fully characterized by NMR and ESI-HRMS analyses. In a Pd-catalyzed aerobicoxidation of 1-phenylethanol, 1a and 1b worked well as carboxylate ligands.
