title: The progress of selective fluorescent chemosensors by boronic acid.
abstract: As a cutting-edge scientific research field, the detection of biological active substance is very important for the prevention, diagnosis and treatment of diseases. Boronic acid interacts with cis-1,2-or 1,3-diol to form five- or six-membered ring which could be used as the reporter of fluorescent sensors to probe carbohydrates and bioactive substance. This review summarizes the recent progress of boronic acid sensors for carbohydrates, L-dopamine, fluoride, copper ion, mercury ion and hydrogen peroxide. In this article, we will briefly introduce the chemistry of boronic acid, and then give a description of the fluorescence properties of each boronic acid sensor, such as fluorescence intensity change, excitation and emission wavelengths, quantum yields and water solubility. In addition, we summarize the mechanisms of fluorescent signal output for some representative sensors and discuss the strategies for developing new fluorescent probes.
