Özet

Metal-free and Co(II)-phthalocyanines carrying eight dodecaborate substituents (96 boron atoms) on the peripheral positions were synthesized in a multistep reaction sequence. The first step of the preparation of metal-free and Co(II) target phthalocyanines was cyclotetramerization of 4-(3,5-dimethoxyphenoxy) phthalonitrile in pentanol in the presence of lithium pentanolate and Co(II) salt, respectively. After cleavage of methyl groups the reaction of (Bu4N)[B12H11O(CH2CH2)(2)O] with hydroxyphenoxy substituted phthalocyanines gives the novel phthalocyanines 7, 8 with eight dodecaborate units. The new phthalocyanine compounds were characterized by NMR, FT-IR and UV-VIS spectral data. The electrochemical investigations of cobalt(II) phthalocyanine together with Zn(II) derivative having identical substituents were studied. (C) 2014 Elsevier B. V. All rights reserved.
