“…Recently, Tanyeli and co-workers drew attention the promising results for photochromic applications of triazole substituted zinc(II) Pc [15]. Kantekin et al studied on the singlet oxygen quantum yield of phthalocyanine complexes substituted with tetra triazole groups on periphery and they have studied the electrochemical properties of 1,2,4-triazole substituted Pcs [16,17]. Bayır and co-workers have recently investigated the electrochemical properties of Pcs that have thiazole substituents containing Cobalt, Zinc and manganese as metal centers [5].…”

P hthalocyanines (Pcs) can be used many different applications such as gas sensors, electrochromic devices, photovoltaic cells and photodynamic therapy (PDT), due to their 18-π planar conjugate electron system [1][2][3][4]. Therefore synthesizing Pcs having different groups play a vital role in promoting these high technologies.These macrocyclic compounds are ideal building blocks for applications when they are modified with groups in the desired properties. For this reason, substitution of Pcs either on peripheral/nonperipheral or axial positions has vital importance for their utilizations. Furthermore, the solubility of Pc derivatives plays a critical role in order to use in all those applications. Phthalocyanines that unsubstituted are not soluble in common organic solvents due to the aggregation. These compounds can be made soluble in organic solvents by integration of substituents in the periphery/non-periphery of Pc core, thus increasing their electrochemical and catalysis applications. [5]. 1,2,4-Triazole derivatives are one of the key organic compound class have an important functions in biological applications. It's known that some of 1,2,4-triazoles exhibit biological trenchancy e.g. antifungal, anti microbial, anti viral, anti tubercular,

“…A utilização do precursor aminoftalimida para a obtenção de uma metaloftalocianina contendo grupos doadores, não foi alcançada. Uma das hipóteses é que a aminoftalimida não consegue completar a reação de condensação, provavelmente por causo da influência do grupo doador NH2 Os principais modos vibracionais referentes ao núcleo base são constituídos por quatro unidades de isoindol ligadas através de ligações de azoto, também presentes no precursor, permaneceram praticamente inalterada na nova metaloftalocianina, já que as ftalocianinas são altamente estáveis eletronicamente (INO, WATANABE, TAKAGI, MATSUMOTO, 2005;DEMIRBAŞ et al, 2016).

“…O espectro eletrônico das metaloftalocianinas, na região do UV-Vis é bem similar ao das metaloftalocianinas, assim como a coloração aparente (AKTAS et al, 2014;DEMIRBAŞ et al, 2016). A banda mais intensa, conhecida como banda Q aparece na região entre 600 a 700 nm, o que caracteriza a coloração azulada desses compostos, refere-se a transições π → π*.…”

“…Esse efeito provoca um deslocamento das bandas Q, com deslocamentos que têm sido interpretados através de um modelo de acoplamento de éxcitons. De modo geral, as espécies monoméricas apresentam bandas Q mais finas, ao passo que as bandas mais largas indicam espécies associadas (AKTAS et al, 2014;DEMIRBAŞ et al, 2016).

The phthalonitrile (3) and triazole substituted metallo phthalocyanines (MPc) (4–7) were prepared. The novel compounds were characterized with spectroscopic data. Electrochemical analyses of metallophthalocyanines (4–7) bearing triazole substituents were performed to investigate redox activity of phthalocyanines (Pcs) ring. While incorporation of Ni2+ and Cu2+ cations in the Pc core only influenced peak positions of Pc ring processes, Co2+ and Cl1−Fe3+ cations of CoPc and FePc gave extra redox couples to the Pc based ones. Releasing the axial Cl1− anion on Fe3+ cation of FePc during the reduction reactions complicated the redox responses. Redox reactions of Co2+ and Fe3+ metal centers also considerable influenced spectral and color responses of these complexes.
