title: An N-substituted aza[14]metacyclophane tetracation: a spin-quintet tetraradical with four para-phenylenediamine-based semi-quinone moieties.
abstract: A fully dianisylaminophenylated aza[1(4)]metacyclophane has been synthesized that exhibits four reversible two-electron oxidation processes, and its dicationic and tetracationic species have been found to be in spin-triplet and spin-quintet states.
