Synthesis, Photophysics and Theoretical Calculation of (E)-2-(benzo[d] thiazol-2-yl)-3-(3-methoxyphenyl)acrylonitrile

Abstract

: A new type of luminogens with aggregation-induced-emission (AIE) behavior was designed and synthesized. The result of single crystal X-ray structure showed a planar structure in which the dihedral angle between two aromatic rings is less than 30o. Moreover, two different intermolecular hydrogen bond interactions supported the stability of crystal structure. After formation of organic nanoparticles in poor solubility solvent, the emission intensity of desired product was increased and the enhancement reached 14-fold. This new design of luminogen provided further understanding for AIE mechanism.
