TL;DR: In this article, a two-component supramolecular organogel with a linear aliphatic diamine in non-hydrogen-bonding solvents is presented.

TL;DR: In this paper, a distannoxane-catalyzed transesterification reaction has been developed which affords various types of esters under very mild conditions and is applied to the stereo and regioselective synthesis of trisubstituted α,β-unsaturated carboxylic acids.

TL;DR: In this article, Picot et al. showed that the carboxylic acid group of flurbiprofen is located in a favorable position for interacting with the arginine 120 residue of prostaglandin G/H synthase (PGHS-1).

TL;DR: FTIR-ATR measurements permit detailed structural analysis and in situ titration of carboxylate-terminated self-assembled monolayers and monomeric and dimeric/oligomeric acid groups are seen, and their acid-base behavior is directly monitored.
Abstract: FTIR-ATR measurements permit detailed structural analysis and in situ titration of carboxylate-terminated self-assembled monolayers. Both monomeric and dimeric/oligomeric acid groups are seen, and their acid−base behavior is directly monitored. Monomers that are hydrogen bonded only to surrounding water molecules have a pKa = 4.9, while the pKa for the aggregated molecules is 9.3.

TL;DR: In this article, a gold-coated quartz crystal microbalance (QCM) electrode or a quartz plate was used for repeated immersion in solutions of C3AzoCO2H and titanium butoxide (Ti(O-nBu)4) in toluene/ethanol.
Abstract: Ultrathin films of titanium oxide gel imprinted with 4-(4-propyloxyphenylazo)benzoic acid (C3AzoCO2H) were prepared by repeated immersion of a gold-coated quartz crystal microbalance (QCM) electrode or a quartz plate in solutions of C3AzoCO2H and titanium butoxide (Ti(O-nBu)4) in toluene/ethanol. Regular film growth was confirmed by frequency decrement in QCM measurements and by the appearance of the azobenzene absorption in UV−vis spectroscopy. The template molecule could be completely removed upon treatment with 1% aqueous ammonia. The resulting films showed saturation binding of the template molecule in acetonitrile in less than 1 min. Binding of the template molecule was greatest among aromatic carboxylic acids that are structurally related to the template. A related ester showed a significant reduction in the binding efficiency. The surface sol-gel process provides a powerful tool for molecular imprinting in ultrathin metal oxide films.
