Selective ether cleavages: simple routes yielding di- and tri-functional hexaalkoxytriphenylenes
Discotic hexasubstituted triphenylene derivatives represent a promising class of materials, e.g. with respect to their photoconductive properties. To tailor the processibility and mesophase behaviour of such materials specifically functionalized cores as precursor molecules for discotic oligomers, polymers and networks or amphiphiles are required. The paper presents various synthetic strategies, all based on selective ether cleavage methods, leading to new highly functionalized triphenylenes.
