The preparation method of a funnel like ligand
derived from calix[6]arene and tris(2-pyridyl-
methyl)anime has been improved. The Cu(II) complex was
obtained and characterized by ESI-MS, EPR, UV-Vis spectra and crystallographic
analysis. In the complex, a guest acetonitrile molecule is introduced into the
cavity of the ligand host via the coordination with Cu(II) center.
