| Abstract: | The proton affinities (PAs) of 1- and 2-azahelicene were determined using various mass spectrometric techniques and complementary results from density functional theory. With PAs of about 1000 kJ mol(-1), the helical backbone of both compounds offer promising perspectives for future research on enantioselective reactions of these helical nitrogen bases. |
