Synthesis and structural properties of the first dodecakis(aryloxy)triphenylenes
摘要:
Dodecaethers 1-3, members of a new class of molecule, were prepared by persubstitution of perfluorotriphenylene 4 by the appropriate phenolate nucleophiles in 1,3-dimethylimidazolidin-2-one (DMEU) as solvent. An exactly C-2-symmetric conformation has been established by X-ray analysis for dodecakis(p-tolyloxy)triphenylene 2 in its molecular crystal, whilst counterpart 3, possessing the more extended p-phenylphenoxy side-chain, is a new host capable of forming crystalline inclusion compounds with guest species such as acetonitrile, and di-, tri-, and tetra-glyme, for example.
