摘　　要：为了满足信息快速发展对数据存储安全的要求,设计并成功合成了一种π-共轭三苯胺基二氟硼化合物(PyTPABF_(2)).Py TPABF_(2)具有正的溶剂化变色行为、分子内电荷转移性质、聚集诱导发射行为和高对比度机械荧光性能.在外部机械刺激和有机溶剂熏蒸下,所制备的PyTPABF_(2)粉末的荧光颜色可在绿色和卡其色间可逆转变,这一现象源于晶态和无定形之间的相变过程.更重要的是,基于PyTPABF_(2)的数据安全纸可以实现信息的可重写存储,有助于智能发光材料的合理设计.In order to meet the demand of data storage security in the rapid development of information,aπ-conjugated triphenylamine-based difluororboron compound(PyTPABF_(2))was designed and successfully synthesized.PyTPABF_(2)held positive solvatochromism behavior,intramolecular charge transfer property,aggregation-induced emission behavior and high contrast mechanofluorochromic performance.The as-prepared powders PyTPABF_(2)exhibited bright green fluorescence(533 nm),which luminescent color switching to khaki(556 nm)under external mechanical stimulation,meanwhile,the color could recover to original state after fuming.The X-ray diffraction(XRD)measurement demonstrated that this phenomenon originated from the process of phase transformation between crystalline and amorphous.More importantly,PyTPABF_(2)-based data security paper could be achieved rewritable storage of information.It was of assistance in the rational design of smart luminescent materials.
