Abstract
An original method based on metal-free ligand and lanthanide acetate direct interaction in the presence of a strong organic base (DBU) is used to prep are sandwich-type gadolinium and ytterbium crown-ether substituted phthaloc yanines bis[4,5,4',5',4 ",5 ",4''',5'''-tetrakis(1,4,7,10,13-pentaoxatridec amethylene)phthalocyaninato]gadolinium (ytterbium) and tris[4,5,4',5',4 ",5 ",4''',5'''-tetrakis(1,4,7,10,13-pentaoxatridecamethylene)phthalocyaninato ]digadolinium (ytterbium) which are characterized by MALDI-TOF mass spectro metry and UV-vis spectroscopy.
