Boronic acid, B,B'-[(1,2-diphenyl-1,2-ethenediyl)di-4,1-phenylene]bis- 4,4'-(1,2-Diphenyl-1,2-ethenylene)diphenylboronic acid

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

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.
