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
