- Abstract
A simple synthesis strategy afforded a family of hydrogen‐bonded azines and Schiff‐bases. Although in dilute solution these dyes are faint light emitters, all exhibit bright luminescence upon aggregation. Changing the peripheral substituents from electron donating to electron withdrawing allows emission fine‐tuning in a range from bluish‐green to orange‐red. The crystal structures of the materials reveal that the restriction of intramolecular rotations is the main mechanism for the aggregation‐induced emission enhancement properties. A rainbow of AIEEgens: Hydrogen‐bonded azines and Schiff bases are non‐emissive in dilute solutions, but exhibit bright luminescence upon aggregation, in a range from bluish‐green to orange‐red.
