“…The fluorescence lifetime result of phthalocyanine 5 was shown in Figure 7. The obtained data are analogous with most of the phthalocyanine derivatives which have different groups and metal atom ions [4]. With lifetime τF=1.71 ns, the fluorescence corruption of phthalocyanine 5 was accomplished in the monoexponential curve.…”

“…Thermal and chemical stability of phthalocyanines and their versatility make these molecules excellent candidates in many areas of materials science [2]. Owing to the advances in this class of compounds and their enhanced abilities in optical, electronic, catalytic, and selfassembling properties, phthalocyanines gained extra importance over the last few decades [3][4].…”

“…The advantage of Schiff bases for the application of sonophotodynamic studies is the conjugation capability of them due to donor lone electron pairs on nitrogen atom (38,39). Two or more bioactive compounds covalently bonded have synergistic effect (40) and photophysicochemical studies of Schiff base substituted phthalocyanines have been reported so far (41–43).…”

Although the sonophotodynamic method has an effective therapeutic outcome for anticancer treatment compared with the photodynamic method, there are not enough related studies in the literature and this study aims to contribute to the development of sonophotodynamic studies. For this purpose, the Schiff base substituted silicon phthalocyanines were designed and synthesized as effective sensitizer candidates and the photophysicochemical and sonophotochemical features of the phthalocyanines were examined to increase singlet oxygen efficiency. The calculated ΦΔ values indicate that the contribution of substituent groups improved the production of singlet oxygen compared with silicon (IV) phthalocyanine dichloride (SiPcCI2) and also the sonophotochemical applications increased the singlet oxygen yields. The ΦΔ values (ΦΔ = 0.76 for axially bis‐{4‐[(E)‐(pyridin‐3‐ylimino)methyl]phenol} substituted silicon (IV) phthalocyanine (2a), 0.68 for axially bis‐4‐[(E)‐{[(pyridin‐3‐yl)methyl]imino}methyl]phenol substituted silicon (IV) phthalocyanine (2b) in photochemical study) reached to ΦΔ = 0.98 for 2a, 0.94 for 2b in sonophotochemical study. This article will enrich the literature on increasing singlet oxygen yield.

“…In literature showed that the introduction of chalcone groups into the peripheral/nonperipheral positions of phthalocyanines increased the electrochemical properties of phthalocyanines [24][25][26][27][28]. Also, phthalocyanines bearing chalcone groups have efficient photocatalytic, photophysical and photochemical properties [29,30]. We wondered how the presence of phthalocyanines in the peripheral or non-peripheral positions of the chalcone group affects the electrochemical properties of phthalocyanine compounds.…”

In this study, new chalcone compound 1, new phthalonitrile derivatives 2 and 3, new copper(II), manganese(III) phthalocyanines bearing chalcone groups at peripheral or nonperipheral positions were synthesized. Electrochemistry of tetra-(4-{(2E)-3-[2-fluoro-4-(trifluoromethyl)phenyl]prop-2-enoyl}phenoxy) substituted Co(II)Pc and Mn(III)Pcs were studied with cyclic voltammetry (CV) to determine the redox properties of the phthalocyanines. According to the results, while the CuPcs 2a and 3a showed two Pc based reduction reactions and one Pc based oxidation reaction, MnPcs 2b and 3b gave two metalbased reduction reactions. All the redox processes are shifted toward positive potentials as a result of the increased electron-withdrawing ability of the trifluoromethyl substituents.
