Novel crown ether-substituted phthalocyanines
A novel macrocycle has been synthesized from 4′-(α-bromoacetyl) benzo-15-crown-5, 4-
nitrophthalonitril and diethyl malonate; its cyclotetramerization gives Cu (II), Co (II) and Pd
(II) phthalocyanines (Pcs) with four benzo-15-crown-5 substituents on the periphery. The
effects of alkali metal cations with these Pcs has been investigated through the changes in
the visible spectra. The newly synthesized compounds have also been characterized by
elemental analyses, IR, 1H NMR.
