Abstract
The reaction of tetra(15-crown-5)-substituted phthalocyaninate of lutetium acetate (I) with sodium and potassium acetates in a CHCl3-DMSO solvent mixt ure was studied by spectrophotometry and H-1 NMR spectroscopy. The crown-et her moiety of I was found to chelate K+ and Na+ ions. The reaction of I wit h K+ results in the formation of coaxial dimers of the "host-guest" type, w hereas the reaction with Na+ yields no dimers of this type.
