The first known homoleptic cofacial dimers, based on covalently linked dibenzotetraaza[14]annulenes, were synthesized in reasonable 35–40% yields, without recourse to high-dilution techniques. Dinuclear zinc(II) dimer showed strong binding affinity toward DABCO. Site-selective monometallation of the dimer, triggered by the linkers' structure, was observed, allowing access to heterobimetallic co-receptors.
