Microwave-assisted synthesis, electrochemistry and spectroelectrochemistry of phthalocyanines bearing tetra terminal-alkynyl functionalities and click approach

摘要: Abstract This work provides a successful, easy and efficient process for the preparation of both symmetrically tetra nonperipheral peripheral terminal alkynyl substituted zinc cobalt phthalocyanines (Pcs) click approach. Two different routes, conventional microwave-assisted synthesis, have been used by direct cyclotetramerization reactions. While novel Pcs were synthesized using only method, very fast, method microwaves has also described synthesis ZnPc complexes. In order to develop phthalimide conjugated phthalocyanine, [2,9(10),16(17),23(24)-tetrakis((1-(2-(1,3-dioxoisoindoline-2-yl)ethyl)-1H-1,2,3-triazol-4-yl)ethoxy)phthalocyaninato]zinc(II), was via reaction. The precursors target complexes characterized comprehensively with 1 H NMR, 13 C FT-IR, UV–Vis spectra together elemental mass analyses. Electrochemical properties examined determine effect position substituents. substitution shifted redox processes toward negative potentials, peripherally gave more reversible processes. On other hand, while Pc ring-based electron transfer reactions metal-based reduction oxidation recorded CoPc complex. Moreover phthalimide–triazole substituent on periphery found affect electrochemical
