Synthesis and Characterization of Phthalocyanines Containing Four 11-Membered Triaza Macrocycles

Abstract

New metallophthalocyanines (M=Cu, Zn, Ni or Co) substituted in peripheral positions with four 11-membered triaza macrocycles are prepared from 1,4,7-tris(p-tolylsulfonyl)-1,4,7-triazaheptane and 1,2-dibromo-4,5-bis(bromomethyl)benzene or the corresponding anhydrous metal salt [CuCN, Zn(O₂CMe)₂, NiCl₂ or CoCl₂].
