The generic structure of our bimesogens is shown in and for a typical blue-phase mixture of the type we describe here we use mixtures of the ratio 33.4% (n =2.6), 34.1% (n =6.57), 36.6% (n = 11.15) with of the high twisted power (HTP) agent BD H1381(available from Merck Chemicals and described in ref. We then studied the electric-field dependency of the selective reflection in BP I* at 20.7 °C by applying increasing and the decreasing pulsed alternating current (a.c.) electric fields (100 Hz).
