Synthesis, characterization and photovoltaic behaviours of peripheral and non-peripheral tetra-[4-(4-octylpiperazin-1-yl)phenoxy] substituted zinc(II), cobalt(II), copper(II) and indium(III) phthalocyanines

Abstract

The synthesis of zinc(II), cobalt(II), copper(II) and indium(III)(OAc) phthalocyanines carrying four 4-(4-octylpiperazin-1-yl) phenoxy moieties in peripheral/non-peripheral positions were performed by the cyclotetramerization of compounds 4-[4-(4-octylpip
