Electro‐optical Memory of a Nanoengineered Amorphous Blue‐Phase‐III Polymer Scaffold

An electro-optical (EO) memory device is presented, which is based on a 3D nanostructured polymer scaffold of the amorphous blue phase III (BPIII) of cholesteric liquid crystals (LCs), which can impart optical isotropy, optical activity, and sub-millisecond EO response of BPIII to conventional nematic LCs. This functional scaffold also enables the first experimental observation of the long debated structure of BPIII.
