Synthesis and chemical behaviour of triple-decker lanthanum tetra-15-crown-5-phthalocyaninate

The triple-decker lanthanum crownphthalocyaninate La₂[(15C5)₄Pc]₃, where [(15C5)₄Pc]^2– is the [4,5,4',5',4'',5'',4''',5'''-tetrakis- (1,4,7,10,13-pentaoxatridecamethylene)phthalocyaninate anion], was found to undergo hydrolytic decomposition in solution, as studied by UV–VIS spectroscopy.
