Abstract

Not only the configuration at the C5 and C6 stereocenters but also the intra/intermoleculer hydrogen-bonding mode are determinant for the sense of mobile helicity of the dihydrophenanthroline unit in the title diols in solution. Thus, drastic changes in chiroptical signals are induced through conformational switching of 1 upon addition of protic solvent and/or acid.
