New compounds (S)-4'-(1-methylheptylo arbur)yl)bipheny1-4-yl 4-[3-(2,2 3,4,4 5,5,5-nur)afluuropentyloxy)Prop-l-o)cy]benzoates were synthesised and characterised. Their mesomorphic properties were tested by means of polarising optical microscopy and differential scanning calorimetry. The multicomponent antiferroelectric high tilt mixture with long pitch has been also formulated and charaterised. The helical pitch of prepared mixture was estimated with selective reflection method.
