In search of the long-pitch orthoconic antiferroelectric liquid crystalline mixture 1-31, 2, 3 with a broad antiferroelectric smectic phase was successfully formulated. The effect of additive of structurally non-compatible antiferroelectric dopant [image omitted] 4 on the phase structure, transition temperatures, and electrooptical properties of an antiferroelectric orthoconic mixture W1000 3 was investigated with thermal, electro-optical, and XRD methods. Experimental data demonstrates that eutectic mixture W1000F obtained by doping of mixture W1000 with highly tilted antiferroelectric dopant [image omitted] maintains the orthoconic properties. The effects of the significant reduction of the rotational viscosity of the admixture is presented and discussed. Comprehensive analysis of parent mixture W1000 and doped mixture W1000F revealed that the [image omitted] affects the intralayer as well as interlayer intermolecular interactions.
