The arrangement of the columns in a liquid crystalline discotic polymer can be made visible by high resolution electron microscopy (see picture on the right). A two-dimensional hexagonal ordering of the columns is observed; specific packing defects can also be detected. These findings are supported by computer processing of the images.—The discotic polymer is formally a polyester of tetrakis(pentyloxy)triphenylenediol and hexadecanoic diacid.
