Conjugation-Induced Rigidity in Twisting Molecules: Filling the Gap Between Aggregation-Caused Quenching and Aggregation-Induced Emission

Conjugation-induced rigidity in twisting molecules provides a new facile but effective avenue toward solution and solid dual-state efficient luminogens. While conjugation rigidifies the molecular conformations in solution, the twisting structure prevents or alleviates detrimental close molecular packing in the solid states, thus synergistically yielding high efficiencies in both solution and solid states.
