Novel phthalocyanines with pentafluorobenzyloxy-substituents

Synthesis and electrochemical and spectroelectrochemical characterization of chloromanganese(III) phthalocyanines

“…Zn, Co, Ni) complexes at the peripheral positions were synthesized 10,11,21,22 and photophysical and electrochemical properties of these MPcs were studied. 7,10,22,23 In the present paper, we describe the synthesis and 4'-pentoxy)benzyloxy groups on the periphery by the 'Li method' in pentanol.…”

Synthesis and EPR studies of a near infrared absorbing tetrakis(2-naphthoxy)vanadylphthalocyanine

“…The range of solubility in phthalocyanines becomes very important for these applications, since many Pcs are poorly soluble in organic solvents and the limited solubility causes difficulties in purification. The solubility of Pcs can be enhanced by adding different kinds of substituents such as bulky or long chain moieties at the peripheral and non-peripheral positions of the phthalocyanine ring [5,6].…”

The solubility of Pcs can be enhanced by adding different kinds of substituents such as bulky or long chain moieties at the peripheral and non-peripheral positions of the phthalocyanine ring [5,6].The Q band of vanadylphthalocyanine (VOPc) has been found to be more red shifted compared to other MPcs [7]. The nature of substituent has been observed to affect the shifting of the Q band of the phthalocyanine, with electron-donating substituents leading to a greater red shift in comparison to electron-withdrawing substituents.…”

New Zinc (II) Phthalocyanines Substituents: Synthesis, Aggregation Behavior, Antioxidant, and Antibacterial Activity

“…Phthalonitrile derivatives 2 and 3 were obtained through the reaction of nucleophilic substitution reaction between 4-nitrophthalonitrile and methyl 2-mercaptoacetate or methyl 3-mercaptopropanoate at room temperature under nitrogen atmosphere in dry DMF in the presence of K 2 CO 3 as a basewith 87% yield (Scheme 1). This reaction has been used in the preparation of a variety of ether or thioether substituted phthalonitriles [20], [21]. Cyclotetramerization of the phthalonitrile derivatives 2 and 3 in a high-boiling solvent npentanol in the presence of a few drops 1, 13 C NMR, mass characterization techniques and UV-vis spectra.…”
