A 2: 2 stilbeneboronic acid-gamma-cyclodextrin fluorescent ensemble highly selective for glucose in aqueous solutions

By designing a long and hydrophobic stilbeneboronic acid (STDBA) and allowing it to be included within the cavity of gamma-cyclodextrin (gamma-CyD) we succeeded in developing a fluorescent 2 : 2 STDBA-gamma-CyD ensemble that shows a selective and sensitive response toward glucose in aqueous solutions, with satisfactory application in artificial urine samples.
