Abstract:Developing security inks, which can be permanently erased after reading
the information, is of great significance in enhancing the information
and data protection of ink anti-counterfeiting applications. Herein, a
novel TPE-derived AIE fluorescent molecule (TPE-PA) is synthesized,
which produces the strongest fluorescence in THF/water (5:95, v/v, the
same below) and EtOH/water (30:70) co-solvents. However, in co-solvents
of equal concentration, the fluorescence of TPE-PA pigment in EtOH/water
(30:70) was almos… Show more
