Abstract

A novel macrocycle has been synthesized from 4'-(alpha-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, H-1 NMR. (C) 2000 Elsevier Science Ltd. All rights reserved.
