Dataset for Enantiopure Boramidine for Detailed (Chir)Optical Studies

Inclusion of boron atoms into chiral π-conjugated systems is an effective strategy to unlock unique chiroptical properties. Herein, preparation and characterization of a configurationally stable axially-chiral boramidine are reported showcasing absorption in the UV domain, deep-blue fluorescence (Φ up to 94%), and ca. |10-3| gabs and glum values. Detailed photophysical studies and quantum-chemical calculations elucidate the deactivation pathways of the emissive state to the triplet excited states, involving increased spin-orbit coupling between S1 and T3.
