Microwave-asissted synthesis and spectral properties of some phthalocyanines containing azo groups

Abstract

The microwave assisted synthesis, characterization of novel peripherally azo dye substituted metallo phthalocyanines (Co(II), Ni(II), Cu(II), Zn(II)) have been reported in this study. All the new compounds were characterized by a combination of  FT-IR, ¹H NMR, ¹³C NMR, and UV–vis spectroscopy techniques. All phthalocyanine compounds are soluble in DMF and DMSO. Aggregation properties of phthalocyanines were investigated at different concentrations in DMSO. Higher aggregation tendency were observed for the metallophthalocyanines (M: Cu, Ni) than other metallophthalocyanines (M: Co, Zn).

Azo grupları içeren bazı ftalosiyaninlerin mikrodalga yardımlı sentezi ve spektral özellikleri

Abstract

Yeni periferal azo grubu bağlı metalli ftalosiyaninlerin (Co(II), Ni(II), Cu(II), Zn(II)) mikrodalga yardımlı sentezi ve karakterizasyonu bu çalışma ile ilk kez sunuldu. Yeni bileşiklerin hepsi FT-IR, ¹H NMR, ¹³C NMR, and UV–vis spectroskopisi teknikleriyle karakterize edildi. Bütün ftalosiyanin bileşikleri DMF ve DMSO içerisinde çözünmektedirler. Ftalosiyaninlerin kümelenme özellikleri DMSO içinde farklı konsantrasyonlarda incelendi. Cu ve Ni içeren metalli ftalosiyaninlerdeki kümelenmenin Co ve Zn içerenlerdekinden daha fazla olduğu gözlendi.
