Matter di usion experiments are carried out in hexagonal columnar phases of mesogenic disk-like and polycatenar compounds. The di usion characteristics of two d y es of di erent sizes di used into these mesophases are determined by measuring the di usion coe cients along the columns and perpendicularly to them. The nature of di usion versus the structure of these mesophases is discussed in comparison with previous results obtained in nematic and smectic systems.PACS numbers: 61.30.v; 62.20.Fe; 66.30.J.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
