In this study, a new type of luminogen 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 the crystal structure. After the formation of organic nanoparticles in poor solubility solvent, the emission intensity of the desired product was increased and the enhancement achieved was 14-fold. This new design of luminogen provided further understanding of the AIE mechanism.

在这项研究中，设计并合成了一种新型的具有聚集诱导发射（AIE）行为的发光剂。X射线单晶结构的结果显示了两个芳环之间的二面角小于30°的平面结构。而且，两种不同的分子间氢键相互作用支持了晶体结构的稳定性。在溶解性差的溶剂中形成有机纳米颗粒后，所需产物的发射强度增加，并且达到的增强效果是14倍。发光剂的这种新设计提供了对AIE机制的进一步理解。
