Abstract: | The phase diagram of a binary mixture of 4-n-octyloxy- phenyl–4′-n-heptylcyclohexane carboxylate (molecule having weak polar terminal group) and 4-nitrophenyl-4′-n-pentylbenzoate (molecule having strong polar terminal group) has been studied using polarizing microscope and differential scanning calorimeter. The phase diagram shows an enhancement in smectic A phase over a wide composition range and intermediate nematic phase in a narrow composition range. The dielectric properties of these phases are investigated in the frequency range of 100 Hz to 1 MHz. |
