We report our latest. results on the development of functional triphenylene derivatives. Functionality can be introduced. directly into the nucleus by, for example, nitration. Analysis of our recently determined, single crystal x-ray structure of 1-nitro-2,3,6,7,10,11-hexaethoxytriphenylene (HAT2-NO2) suggests that the introduced dipole contributes significantly to the stability of the columnar structure. Synthesis of selectively hydroxylated alkoxytriphenylenes allows the functionalisation of one or more side-chains and we show examples of this in which the functional side-chain is: ethyleneoxy or ester or the side chain carries moieties such as: TTF, fullerene or crown-ether. The final section details new findings on crown-ether terminated hexaalkoxytriphenylene derivatives, which form lyotropic lamellar phases.
