Novel pyrazole functionalized phthalocyanines and their first row transition metal complexes

Photophysical Processes Occurring in a Zn-phthalocyanine in Ethanol Solution and on TiO2 Nanostructures

“…46 The 2e g level is split into two different levels of lower symmetry. This rearrangement, explained in previous studies in terms of distortion effects, [42][43][44]46,47 becomes even more evident (around 20 nm splitting) due to the intrinsic asymmetry introduced by the phenyl-ethynyl moiety in the molecule of the present study. The precise central wavelength of each peak is achieved by a fitting procedure: the complete fitting analyses of the visible spectra are reported in Figure S1 and Table S1 of the Supporting Information (SI).…”

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. Interest to such substituents is caused by various biological activity of the pyrazole derivatives (antimicrobial, [34] antipyretic, [35] analgesic, [36] anti-inflammatory, [37] antiviral [38] and other properties [39] ).…”

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

“…[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. [18] Interest to such substituents is caused by various biological activity of the pyrazole derivatives (antimicrobial, [19] antipyretic, [20] analgesic, [21] antiinflammatory, [22] antiviral [23] properties and others [24] ).…”
