Popis:	Reported here are the unique properties of N,N′,N′′-(3,4,5-tridodecyloxyphenyl)benzo[b,b′,b′′]tristhiophene-2,2′,2′′-tricarboxamide 3 as a new H-bonded discotic liquid crystal. Polarized optical microscopy and thermal analysis as well as variable temperature IR spectroscopy and X-ray diffraction confirm the presence of two thermotropic H-bonded hexagonal columnar mesophases that cover a temperature range from
