Confocal Laser Scanning Microscopic Observation of Polymer-Stabilized Blue Phase I

Abstract

The structure of the polymer-stabilized blue phase I with a cubic structure of the order of optical wavelength was observed by the confocal laser scanning microscope. The spacing of a striped pattern observed in the (110) plane of the polymer-stabilized blue phase I was a couple of hundred nm, which agreed to the interval of the ordered double twisted cylinders estimated based on a well-known model of blue phase I with O8 symmetry.
