Abstract / Bemerkung
We synthesized the new supramolecular host molecules 7 and 13 based on functionalized resorcarenes bearing Kemp's triacid. Conformations in solution have been investigated and the influence of intra-and intermolecular hydrogen bonds from the triacid was shown by low temperature and DOSY NMR experiments. The results of host 7 are supported by DFT calculations. The binding behaviour of 7 towards different 2-amino pyridincs in chloroform has been investigated by NMR titrations. The association constants reach from K 207 M-1 for 2-amino-5-cyano pyridine to K=1551 M-1 for 2-amino-4-methyl pyridine. The association constants of the formed complexes of 7 with 2-amino pyridines were compared with those of the simple host systems 14 and 15 in order to evaluate the influence of the attached resorcarene host.
