Novel discotic mesogen: synthesis and liquid crystalline behavior of TAAB (tetrabenzo[b,f,j,n][1,5,9,13]tetraazacyclohexadecine) derivatives with long alkoxy chains

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.
