Luminogens for Aggregation‐Induced Emission via Titanium‐Mediated Double Nucleophilic Addition to 2,5‐Dialkynylpyridines: Formation and Transformation of the Emitting Aggregates

Invited for the cover of this issue are Lutz H. Gade, Claudia Backes, and co‐workers at Heidelberg University. The image depicts 2‐(1,2,2‐triarylvinyl)‐pyridines, which are luminogens for aggregation‐induced emission which “light up” upon irradiation.
