Novel charged [1(4)]ăzolophanes: associative behaviour revealed by electrospray ionization.
Electrospray ionization mass spectrometry has been used to investigate simple multicharged [1(4)]heterophanes containing heterocyclic betaine subunits as building blocks. The formation of stable noncovalent polymolecular self-assembled structures in the gas phase is reported.
