Novel C(3)-symmetrical heteroaromatic hexaazatrinaphthylene (HATNA) gelators symmetrically end-substituted with pendant aromatic and aliphatic amines were synthesized. Some of these π-conjugated structures induce self-assembly, forming fibers able to gelate solvents of different polarity at low wt% as demonstrated by spectroscopic and microscopic techniques.

We report for the first time the discovery of the gelation properties of Hunter's oligoamide with pendant amino groups, 1, which possesses structural features different to some conventional gelators. the organogels were studied with infrared spectroscopy, transmission electron microscopy, and differential scanning calorimetry. Remarkably, the effective self‐assembly process of this oligoamide to produce stable organogels occurs exclusively in chlorinated solvents. (© Wiley‐VCH Verlag GmbH & Co.
