Popis: Based on structural studies already available for the cocrystals of a sterically-rigidified tetraarylpyrene (TP) host substituted at the periphery by flexible methoxymethyl (MM) groups, i.e., TPMM, with aliphatic guests, formation of ternary or three-component cocrystals was targeted by replacing one of the guest species in the binary cocrystals with a different guest. Ternary cocrystals of TPMM with cyclododecene + cyclodecane, cyclododecene + cyclooctane and cyclododecene + decalin pairs were indeed successfully isolated and characterized by single-crystal X-ray structure determination. The ternary cocrystals, in principle, constitute ‘isomorphous pseudopolymorphs’ of binary cocrystals of TPMM with cyclododecene.
