Novel aggregation-induced enhanced emission fragrant molecule found

Aggregation-induced enhanced emission (AIEE) molecules, novel luminescent supplies with excessive solid-state emission efficiencies, are vital within the purposes of optoelectronics, biomedical probes and chemical sensors.

Most fragrant AIEE molecules have advanced buildings consisting of a number of fragrant rings and/or polycyclic skeletons.

Recently, Prof. Qing Guangyan’s group from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) discovered that 2-aminophenylboronic acid (2-APBA) with a easy construction was extremely emissive within the solid state. They additional revealed that 2-APBA exists in a dimeric type, and the 2-APBA dimer is a novel AIEE molecule.

This work was printed in Chemical Science on August 18.

“We are glad to find that a small and simple molecule, because of the ordered aggregation, could emit extraordinary strong fluorescence with high absolute quantum yield,” stated Prof. Qing.

The researchers utilized 2-APBA in sensing CO₂ based mostly on its reversible AIEE fluorescence quenching and restoration, and disclosed new sorts of dynamic covalent B-N and B-O bonds. They proposed a technique to manufacture a CO₂-responsive nano-gating system based mostly on the dynamic covalent B-N and B-O bonds.
