Synthesis, aggregation-enhanced emission, polymorphism and piezochromism of TPE-cored foldamers with through-space conjugation

A series of new folded tetraphenylethene derivatives with different substituents are stereoselectively synthesized, which exhibit interesting through-space conjugation, aggregation-enhanced emission, polymorphism and piezochromism properties. Alteration of intermolecular stacking geometry of a throu...

Zusammenfassung:A series of new folded tetraphenylethene derivatives with different substituents are stereoselectively synthesized, which exhibit interesting through-space conjugation, aggregation-enhanced emission, polymorphism and piezochromism properties. Alteration of intermolecular stacking geometry of a through-space conjugated foldamer gives rise to blue and cyan fluorescent crystals.
