“…The Q band is assigned as HOMO‐LUMO transition, while B band corresponds to the transition from the deeper level of HOMO to LUMO level. Especially Q bands observed as a sharp band at the range of 650–720 nm is important evidence of the presence of phthalocyanine [10a, 13]. In this study, UV‐vis spectra of phthalocyanines were recorded in chloroform and obtained sharp and intense peaks.…”

In this study novel peripherally tetra 1,3‐diethoxy‐2‐propanol substituted Co(II), Cu(II), Mg(II), Ni(II) Zn(II) phthalocyanine derivatives were prepared. The characterization of the novel compounds was made by FT‐IR, 1H‐NMR, UV‐vis and MALDI‐TOF mass. Electrochemical, in‐situ spectroelectrochemical and electrocolorimetric measurements have been carried out with the aim to determine the redox properties, to illuminate reaction mechanism and the effect of substituent and metal center. Moreover, the color properties and aggregation tendency of compounds were also investigated.

“…The main cytotoxic product of photosensitization in the presence of phthalocyanines is assumed to be singlet oxygen [21]. The experiments which are concerning evaluation of singlet oxygen production rate for the new phthalocyanines were carried out by indirect chemical method with a compound of generated singlet oxygen [22].…”

Four mestranol moieties were chemically linked to Zn(II) phthalocyanine (4) by cycloaddition “Click” reaction using a tetra-azidoethoxy substituted Zn(II)-phthalocyanine (3). The alkyl-azido coupling reaction was realized between azido groups of 3 and alkyl group of mestranol. The alkylation reaction was carried out to obtain cationic Zn(II) phthalocyanine derivative (5). The new compounds were chemically characterized by the known analytical methods. The absorption and fluorescence properties were studied in comparison. The absorption maxima of phthalocyanines 3, 4 and 5 were recorded at approx. shifts of 8 - 12 nm in the far- red region (680 - 684 nm) and the fluorescence maxima (692 - 693 nm) as compared to unsubstituted ZnPc (672 nm, 680 nm) in DMSO. The studies of singlet oxygen generation of 3, 4 and 5 showed relatively high values such as 0.52 for 3; 0.51 for 4 and 0.46 for 5. The fluorescence lifetime of 3.15 ns (3), 3.25 ns (4) and 3.46 ns (5) were determined with lower than the value than for the used standard ZnPc (3.99 ns). The high photo stability was observed for compounds 3, 4 and 5. In addition, the photosensitized oxidation of cholesterol was compared for 3 and 4 with much lower values of oxidation potential than for unsubstituted ZnPc which suggests that the substitution groups influenced on the photooxidation index of the target molecule.
