General description

Aggregation-induced emission luminogens (AIEgens) such as tetraphenylethene (TPE) functionalized with boronic acids form luminogen (TPE-BA). TPE-BA can form oligoboronates with D-glucose. Other sugars also form monoadduct with TPE-BA, but once such a complex is formed there is no more cis-diol that allows the oligomerization reaction to proceed, resulting in a very low emission intensity. Thus, TPE-BA could serve as a glucose-specific probe.

Application

TPE-BA is an aggregation-induced emission (AIE) dye for use in Suzuki reaction and D-Glucose detection.

Yi Liu et al.
Journal of the American Chemical Society, 133(4), 660-663 (2010-12-22)
A conceptually new "light-up" biosensor with a high specificity for d-glucose (Glu) in aqueous media has been developed. The emission from a tetraphenylethene (TPE)-cored diboronic acid (1) was greatly boosted when the fluorogen was oligomerized with Glu because of restriction
