Abstract

The self-condensation of 3,4-dialkoxy-2-aminobenzaldehyde (alkoxy = n-C₈H₁₇O, n-C₁₀H₂₁O and n-C₁₂H₂₅O) in the presence of HBF₄ gives the tetrafluoroborate salt of diprotonated octaalkoxy-TAAB which exhibits a hexagonal columnar mesophase over a wide range of temperatures including room temperature.
