ABSTRACT
Molecules with Aggregation-Induced Emission (AIE) effects could show strong emission in solid or aggregate form, thus they are suitable for applications in the field of solid luminescent materials. According to former reporting, AIE molecules are always J-aggregates. In this study, a new benzotriazole derivate with electron donor-acceptor structure was synthesized. (E)-4-(2-(1H-benzo[d] [1,2,3] triazol-1-yl) vinyl)-N, N-dimethylaniline (BTADA) has both TICT and AIE effect, even though it is H-aggregate. Furthermore, BTADA could respond to proton in solution and solid form. Due to its multiple binging sites, proton would bind to benzotriazole and dimethylaniline moiety successively when BTADA was exposed to acid, and the fluorescent color changed from green to yellow then blue as the concentration of proton increased. Such phenomena indicate BTADA has potential usage in proton detection.
