Mono- and di-boranil-substituted helicenes were prepared by BF2-borylation of the corresponding anils, readily synthesized condensation 2-amino- 2,15-diamino-helicenes with 4-(diethylamino)salicylaldehyde. After enantiomeric resolution using HPLC, their chiroptical properties including circularly polarized fluorescence in solution PMMA films investigated rationalized help NMR, X-ray quantum-che...
