New functionalised derivatives of hexaalkoxytriphenylene

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.
