Synthesis, characterization, spectral and electrical properties of peripherally tetratriazole-substituted phthalocyanines and its metal complexes

Synthesis and Isolation of 2,9,17,23-Tetrakis[(3,5-dimethyl-1H-pyrazol-1-yl)phenoxy]phthalocyanine and Its Magnesium(II) and Zinc(II) Complexes

“…[17][18][19][20][21][22][23][24][25][26][27] These substituted phthalocyanines can be highly efficient photosensitizers of singlet oxygen due to dual or synergistic therapeutic effect. [28,29] However, only a few works devoted to phthalocyanines [30][31][32] and porphyrin [33] containing pyrazole substituents are known.…”

Synthesis, characterization and aggregation and fluorescence properties of novel highly soluble zinc phthalocyanines bearing tetrakis-4-(3-(piperidin-1-yl)phenoxy) with tetra and dodecachloro substituents

“…Aggregation of MPcs in aqueous and non-aqueous solution is well known phenomena of phthalocyanine chemistry [35][36][37][38][39][40][41]. Aggregation is usually described as a co-planar association of macrocyclic ring and progressing the formation of monomer to dimmers and higher order aggregates.…”

“…However, the aggregates of MPcs in organic solvents also reported [35][36][37][38]. The aggregation of MPcs has been controlled by different methods such as introduction of substituents at peripheral and non-peripheral positions and octahedral co-ordination of the central metal ion [39][40][41]. The aggregate formation of MPcs depends on the concentration and nature of solvent, metal ion and substituents [35][36][37][38][39][40][41].…”

The aggregate formation of MPcs depends on the concentration and nature of solvent, metal ion and substituents [35][36][37][38][39][40][41]. In the present work, we have synthesized new zinc phthalocyanines bearing tetrakis-4-(3-(piperidin-1-yl)phenoxy)-with tetra (4) and dodecachlorloro (5) substituents.…”

Synthesis of 4-(4-hydrazinylphenoxy)phthalonitrile and phthalonitriles on its basis containing N-heterocycles

“…In the last decade intensive increase of number of the papers devoted to phthalocyanines, containing various nitrogen heterocycles is observed. [12][13][14][15] A number of the works devoted to synthesis of phthalocyanines containing the pyrazole fragments are known. These substituents are attached to a linked phthalocyanine macroheterocycle directly, [16] through the methoxy spacer moiety [17] or through oxygen atom spacer moiety.…”
