ESI-MS STUDY OF CALIX4ARENE DERIVATIVES AND THEIR COMPLEXES

Calixarenes have received a great deal of attention as host molecules in supramolecular chemistry. An important feature of these compounds is their synthetic flexibility. Chemical modification of lower or upper calixarene rims by introducing groups with different binding abilities enables them to form inclusion complexes with a wide variety of guest species. Depending on the appended groups and the number of repeating phenolic units (usually 4 or 6), which defines a macrocycle cavity size, functionalized calixarenes are suitable receptors for alkali, alkaline-earth, transition and heavy metals cations, anions, neutral and chiral molecules. Complex formation can be investigated by different spectroscopic techniques including NMR, UV-Vis, vibrational and luminescence spectroscopy. This talk will be focused on electrospray mass spectrometry (ESI-MS) investigations of calix[4]arene derivatives bearing tryptophan or phenyl-glycine units at the lower rim. The binding properties of these compounds towards lanthanide (La3+, Ce3+, Eu3+ i Yb3+), and alkali metal cations (Li+, Na+, K+) in acetonitrile will be examined and results will be compared with those obtained by ″traditional″ methods. Fragmentation pathways of investigated peptidocalixarenes and their complexes will be given as well.
