The interaction of twelve paracyclophane bisazomethynes with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in dichloromethane is described in terms of formation of 1:1 charge-transfer (CT) complexes.Association constants and transition energies of these CT complexes as well as ionization potentials of the donors 1-3 have been determined.On the basis of association constants and wavelengths of maximum absorption, the basicity of the donor 1-3 follow the order; pseudo-gem (1) > pseudo-meta (2) > pseudo-para (3), which could be rationalized in terms of the existence of transannular electronic interactions in this donor system.
