Abstract: A photoactivatable caged compound (TPE-C) with AIE characteristics is designed and synthesized. TPE-C is non-emissive either in solution or in aggregated state, but its luminescence can be induced to emit strong cyan emission in aggregated state by UV irradiation. Such property enables TPE-C to be applied in photo-patterning and anti-counterfeiting related areas.
