Dimorphic biphenyl based Michael addition product displayed AIE in ethanol–water system and solid state owing to its highly twisted conformation. The quasi-isostructural nature of the two polymorphs resulted identical photo-physical behaviours.

Enantioselective C-H addition is one of the most straightforward and efficient approaches towards synthesis optically active molecules from readily available arenes. The significant feature these reactions that nucleophilic aryl metal species generated catalytically in situ via C–H bond activation. These typically proceed without requirement either strongly basic or acidic conditions, thus with...
