文摘
- •
A dithienopyrrole-based triphenylamine luminogen has been synthesized.
- •
It exhibits reversible mechanochromic luminescence in the solid state.
- •
The oxidized species show redox-switchable near-infrared absorptions in solution.
- •
There exists considerable electron delocalization during the oxidation process.
