The syntheses and conformational structures of various functionalized tetraoxacalix[2]arene[2]triazines were studied. Applying the fragment coupling approach and the post-macrocyclization chemical manipulations, a number of tetraoxacalix[2]arene[2]triazines that contain, on the lower rim, one or two aldehyde, ester, carboxylic acid, hydroxymethyl, and aminomethyl functional groups were prepared in

Self-complementary building units of carboxylate head-containing oxacalix[2]arene[2]triazines were synthesised by inserting different flexible linkers in between the macrocyclic skeleton and carboxylate. The anion- directed self-assembly of these building units in solution and in gas phase was systematically investigated by concentration and temperature variable H-1 NMR, diffusion-ordered NMR spectroscopy (DOSY), dynamic light scattering (DLS) and ESI-MS.[GRAPHICS].
