Cross-condensation of two different phthalonitriles, namely 4,5-bis [(4-methyloxycarbonyl)phenoxy] phthalonitrile (1) and 4-{2-[2-(2-methoxyethoxy)ethoxy]ethoxy)phthalonitrile(2), in the presence of Zn(OAc)2·2H2O and 1,8-diazabicyclo[5.4.O]undec-7-ene (BU) followed by transesterification in refluxing n-pentanol afforded six phthalocyaninato zinc II complexes modulated with different numbers of pentyloxycarbonyl and/or triethylene glycol monomethyl ether groups. Simple silica-gel column chromatography leads to the successful separation of all these six compounds, namely Zn[Pc(BP)4](3), Zn[Pc(BP)3(TEG)](4), Zn[Pc(BP)2(TEG)2]-opp(5), Zn[Pc(BP)2(TEG)2]-adj (6), Zn [Pc (BP) (TEG)3] (7), and Zn [Pc (TEG)4] (8). In addition, the six complexes have been characterized with elemental analysis, MAL I-TOF mass, UV-Vis spectroscopy, 1H NMR, and 2 COSY spectroscopy. The electrochemical properties have also been investigated.
