A route to triptycenes substituted with one, two, five, and six paraffinic chains was developed using the Diels-Alder reaction as the key reaction. 1,4,5,8-Tetrakis(dodecyloxy)-11-hydroxy-14-(dode-canoyloxy)triptycene, 1,4,5,8-tetrakis(dodecyloxy)-11,14-bis(dodecanoyloxy)triptycene, and 1,4,5,8-11,14-hexakis(dodecyloxy)triptycene were obtained in a nine-step procedure starting from diaminoanthrarufin. The five-chain derivative demonstrates original mesomorphic properties.

Two examples of triptycene-based epitaxygens, in which aliphatic chains and aromatic cores form symmetry compatible lamellar lattices, have been synthesized and their mesomorphic properties have been studied.
