Abstract

Based on a regioselective tris-formylation of a tribenzotriquinacene (TBTQ) hydrocarbon, the racemic <i>C</i><sub>3</sub>-symmetrical TBTQ-trialdehyde and the corresponding TBTQ-trimethanol were synthesized along with their <i>C</i><sub>1</sub>-isomers. Conversion of the <i>C</i><sub>3</sub>-trialdehyde to three diastereomeric TBTQ-based cryptophanes occurring in high yield enabled the preparation of the optically pure <i>C</i><sub>3</sub>-symmetrical TBTQ-trialdehydes and the determination of their absolute configuration. The racemic <i>C</i><sub>3</sub>-symmetrical TBTQ-trimethanol was found to form several stable nanotubular aggregates in the solid state
