Abstract:
Combined interaction of triple hydrogen bonding, dipolar pi-pi aggregation and micro-segregation in a melamine-barbituric acid dye assembly leads to a columnar mesophase which could be characterized by optical polarising microscopy, differential scanning calorimetry and X-ray diffraction.
