Planarity‐Controlled ESIPT Versus Cu(II) Coordination in a Hydroxyl‐Rich Schiff Base: Structural Modulation of Excited‐State and Emission Properties
Strategic control of molecular conformation is key to tuning excited‐state processes in functional organic chromophores. Here, the (E)‐4‐(((3‐(hydroxymethyl)phenyl)imino)methyl)benzene‐1,2,3‐triol ( 1K HBAB) was synthesized and investigated via experimental and theoretical approaches. SCXRD confirms the stabiliza...
