Spectroscopic insights on imidazole substituted phthalocyanine photosensitizers: Fluorescence properties, triplet state and singlet oxygen generation

Photodynamic efficiency of hypericin compared with chlorin and hematoporphyrin derivatives in HEp-2 and Vero epithelial cell lines

“…A standard and A PS are the relative absorbance of the standard and the photosensitizer at the excitation wavelength, respectively. Finally, n 2 and n 0 2 are the refractive indices of the solvents for the sample and standard, respectively [23]. Rhodamine B (˚f = 0.65) in ethanol was employed as the standard [24].…”

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 Visible Photocatalytic Performance of Iron (III) Tetracarboxyphthalocyanine-Sensitized TiO2 Photocatalyst

“…Quantum chemistry shows that the formation of the Q and B-bands are attributed to the a 1u (π) →e g (π*) and a 2u (π)→e g (π*) electronic transitions [24,25]. FePc(COOH) 4 exhibited strong Q-band and B-band adsorptions at λ max =673 nm and 331 nm, respectively ( Figure S1).…”
