A selection of dimeric tetraethynylethenes (TEEs) and perethynylated expanded radialenes, containing different donor/acceptor substitution patterns, have been prepared and fully characterized. The first X‐ray crystal structure of an expanded [6]radialene, with twelve peripheral 3,5‐di(tert‐butyl)phe...
