We have prepared two series of hexasubstituted triphenylene derivatives : hexaethers from CH3 to C13H27 and hexaesters from C3H7 to C13H27. Most of them exhibit a thermotropic mesophase with a large temperature range. We have found the existence of an additional transition within the mesophase domain of some hexaesters with long alkyl chains. The structure of this new type of liquid crystal is discussed with respect to ours results concerning miscibilities and heat of transition
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.
