Abstract

Two new AIE-active dinuclear Schiff base Ir(III) complexes exhibit highly reversible piezochromic phosphorescence behaviour enabling the construction of a re-writable phosphorescence data recording device.

Highlights

  • Two new Aggregation-induced emission (AIE)-active dinuclear Schiff base Ir(III) complexes exhibit highly reversible piezochromic phosphorescence behaviour enabling the construction of a re-writable phosphorescence data recording device

  • Aggregation-induced emission (AIE) in the solid or aggregated state, which is the opposite of aggregation-caused quenching (ACQ), was first reported by Tang et al in 2001.5 Recently, a number of pure organic fluorescent small molecules have been shown to simultaneously exhibit AIE and piezochromism.[6]

  • Chi et al proved that the positive effect of AIE on luminescence enhancement may provide a direction for the development of more efficient piezochromic materials.[7]
