Novel water-soluble, deca-substituted pillararenes containing thiasulfate and thiacarboxylate fragments were synthesized and characterized. UV-vis, 2D 1H- 1H NOESY and DOSY NMR spectroscopy revealed the ability of pillararenes containing thiasulfate fragments to form an inclusion complex with cholecalciferol (vitamin D 3) in a 1 : 2 ratio (lg K ass= 2.2). Using DLS and SEM it was found that upon concentration and/or evaporation of the solvent, the supramolecular polymer (pillararene/vitamin D 3(1 : 2)) forms a porous material with an average wall diameter of 53 nm. It was shown that the supramolecular polymer is stable during photolysis by UV radiation (k 1= 1.7 × 10 −5s −1).
