Özet
Bu çalışmada, ter-butil4-(4-(3,4-disiyanofenoksi)fenil)piperazin-1-karboksilat grubu ihtiva eden yeni Zn(II) ve kobalt(II) ftalosiyanin kompleksleri elde edilerek, yapıları karakterize edilmiştir. Her iki kompleks te, DMF, DMSO, THF ve CHCl3 gibi polar çözücülerde çözünmektedir. Komplekslerin farklı çözücü ve konsantrasyonlarda agregasyon özellikleri de incelenmiştir. DMF, DMSO ve THF çözücülerinde 1.10-5 M konsantrasyona kadar her iki kompleksinde agregasyona uğramadığı, fakat CHCl3 çözücüsünde agregasyona uğradıkları gözlenmiştir. Ayrıca komplekslerin elektrokimyasal özellikleri dönüşümlü voltametri ve kare dalga voltametri teknikleriyle incelenmiştir.
In this manuscript, novel zinc (II) and cobalt (II) phthalocyanine complexes (ZnPc and CoPc) modified with tert-butyl 4-(4-(3,4-dicyanophenoxy)phenyl)piperazine-1-carboxylate substituents have been prepared and characterized. These complexes are solouble in many organic solvents such as DMF, DMSO, THF and CHCl3. Aggregation properties of complexes were examinated in different solvents and different concentrations. Spectroscopic evaluation of the Pcs showed a monomeric behaviour evidenced by a single Q band for ZnPc and CoPc up to 1 .10-5 mol dm-3 in DMF, DMSO and THF as typical of metallo Pcs. In all studied organic solvents except CHCl3, ZnPc and CoPc complexes were non-aggregated. Cyclic and square wave voltammetries were used to evaluate the electrochemical properties of the synthesized complexes. Cyclic voltammetry showed two reduction couples and one oxidation peak for the two phthalocyanine complexes.
