New heterocyclic derivatives of dibenzo-18-crown-6 (DB18C6), the products of coupling of kojic acid (5-hydroxy-2-hydroxymethyl-gamma-pyrone) with 4'-DB18C6-yldiazonium chloride, 4',4'''- and 4',5'''-DB18C6-diyldiazonium dichlorides and products of heterocyclization of DB18C6 mono- and dicarboxylic acids with thiosemicarbazide are prepared. Their structures are studied by the methods of H-1 NMR and IR spectroscopy. Polyphosphoric acid is found to be the best agent for the heterocyclization of thiosemicarbazide with DB18C6 carboxylic derivatives. It is proven that the parent substrates, the DB18C6 mono or dicarboxylic acids, serve as phase transfer catalysts for the heterocyclization reaction. Extraction and transport properties of the obtained compounds in respect of potassium, sodium and ammonium picrates are explored.

The discovery of crownethers and their unique interactions with ions make them play a key role in supramolecular chemistry. In this study, we have developed a new type of amphiphilic crownether (DB18C6, DB24C8)-conjugated phenylalanine dipeptides for the gelation of water at physiological pH. We report here for the first time that the size of the crownether controlled the morphology of the self-assembled
