Optically Active 2‐Azatriptycene Bearing a 1‐Pyrenyl Unit Exhibiting Acid‐Induced CPL Switching With Sign Inversion
Abstract
ABSTRACT Optically active 2‐azatriptycene 1 bearing a 1‐pyrenyl unit was synthesized. The resolved enantiomers exhibited blue circularly polarized luminescence (CPL) in solution, with dissymmetry factor g lum on the order of 10 −4 –10 −5 . In contrast, the corresponding protonated species 1H + exhibited green CPL with reversed sign, demonstrating that optically active 2‐azatriptycene functions as an acid‐responsive chiral switching unit.
