Abstract
In this paper, we demonstrate a controllable optical activity emerging as electric-field-dependent circular dicroism (CD) and optical rotatory dispersion (ORD). Such controllable optical activity may offer fascinating possibilities for the production of novel optical materials/devices. The result also supports our previous result about the formation of the chiral superstructure of the 5CB molecules in the BX phase of the 5CB/P8-O-PIMB mixture system.
