✦ Synopsis

The induction of blue phases (BPS) was observed in binary mixtures comprismg nematogcnic compounds and cholesteryi esters which do not exhibit BPS by themselves. Phase diagrams and critical pitches pc above which no BP occurs were determined. Ifp < pc two BPS were observed. In mixtures with pitches close below pc only one BP Seems to exist.

The electric field effect on the transition of the liquid-crystalline blue phase I( BP I) to the cholesteric phase has been investi-Sated. This field-induced transition can be overvoltaged. This effect is equivalent to the BP I supercooling and is caused by a kinetic hindrance of the molecular rearr
