Fig. 5. Effect of the alkoxy-chain length (n) of the pyridine-based derivatives (In) on mesophase behavior of the 1 : 1 supramolecular hydrogen-bonded complexes, (a) m = 8; (b) m = 10; (c) m = 12: (d) m = 14, TCr1–Cr2 = crystal 1 to crystal 2 transition (○); TCr2–SmC = crystal 2 to smectic C phase transition (◊); TSmC–N = smectic C to nematic transition (●);TN–I = nematic to isotropic liquid transition (□).
