Saccharides and temperature dual-responsive hydrogels have been prepared based on PNIPAAm copolymers containing phenylboronic acid (PBA) groups and used for harvesting cell sheets. The cell sheet could be released from the hydrogel layer at 37 °C simply by increasing sugar concentration, and could be more efficiently released at a lower temperature and elevated sugar concentration.

Saccharides in water are detected electrically using an extended-gate type organic field effect transistor (OFET) functionalised by a phenylboronic acid monolayer. The response patterns of the monosaccharides are significantly different, suggesting that OFET devices can successfully read out the saccharide recognition behaviour of boronic acids and be potentially applied to healthcare devices m...

4-Carboxy Phenylboronic acid (4-cpba) was investigated theoretically and experimentally by spectroscopic methods such as FT-IR Raman. The molecular structure parameters were determined computational methods. dimer1, dimer2 trimer structures for intermolecular hydrogen bonding. Moreover, minimum conformational energy search carried out potantial surface (PES). Potential distribution analysis of ...

The rodlike M13 viruses with chemically decorated phenylboronic acid moieties form pH responsive chiral nematic liquid crystal (LC) phases. Binding with biologically important diols results in LC phases with microstructures that closely correlate with the molecular structure of the diols and can be conveniently discerned by visual cues.

This report details the synthesis and characterization of the first chiral diNHC cyclophane ligand and its palladium allyl complex. The complex was tested for 1,4-conjugate addition of phenylboronic acid to 2-cyclohexen-1-one and provides R-3-phenylcyclohexanone in 50% enantiomeric excess.

Dye displacement assays are a simple but effective method to determine the concentration of target analytes. Previously, we have shown that phenylboronic acid pinacol ester hydrogels (borogels) can be used to develop a boronic acid-Alizarin red S dye displacement assay for the determination of fructose (orange to red). In this work, benzoxaborole hydrogels (BOBgels) were developed, and these BO...

The catalytic activity of Au nanoparticles in phenylboronic acid-containing polymer microgels can be tuned through the swelling-deswelling transition of the microgels in response to changes in glucose concentration. Upon adding glucose, the model catalytic reduction of hydrophilic 4-nitrophenol is accelerated, while the reduction of relatively more hydrophobic nitrobenzene slows down.

The multicomponent reaction of 1,2-di(4-pyridyl)ethylene, catechol, 3,5-bis(trifluoromethyl)phenylboronic acid and 1,5-dinaphtho-38-crown-10 or bis-para-phenylene-34-crown-10, respectively, resulted in the formation of rotaxanes, which were characterized by X-ray crystallography.
