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(PyTPABF2). PyTPABF2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PyTPABF2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PyTPABF2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.

Abstract

In order to meet the demand of data storage security in the rapid development of information, a π-conjugated triphenylamine-based difluororboron compound (PyTPABF2) was designed and successfully synthesized. PyTPABF2 held positive solvatochromism behavior, intramolecular charge transfer property, aggregation-induced emission behavior and high contrast mechanofluorochromic performance. The as-prepared powders PyTPABF2 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, PyTPABF2-based data secu-rity paper could be achieved rewritable storage of information. It was of assistance in the rational design of smart luminescent materials.

Key words： triphenylamine-based difluororboron compound; mechanofluorochromic behavior; data security protection
