Comparative studies of photophysical and electrochemical properties of sulfur-containing substituted metal-free and metallophthalocyanines

Nipagin-Functionalized Porphyrazine and Phthalocyanine—Synthesis, Physicochemical Characterization and Toxicity Study after Deposition on Titanium Dioxide Nanoparticles P25

“…The herein reported Pc 3 was a more efficient 1 O 2 generator, with the Φ ∆ equal to 0.29 and 0.13 in DMF and DMSO, respectively, in comparison to Pz 7 , which revealed low Φ ∆ values equal to 0.02 and 0.09 in DMF and DMSO, respectively. These Φ ∆ values were in agreement with previous studies, in which phthalocyanines were found to be more efficient singlet oxygen generators compared to porphyrazines [ 47 , 48 ], especially sulfanyl porphyrazines [ 7 ]. Pc 3 revealed a lower singlet oxygen formation quantum yield in comparison to the reference compound—unsubstituted ZnPc.…”

Dual-purpose zinc and silicon complexes of 1,2,3-triazole group substituted phthalocyanine photosensitizers: synthesis and evaluation of photophysical, singlet oxygen generation, electrochemical and photovoltaic properties

“…17 Chemical structure of substituents which are attached to the peripheral or non-peripheral positions of phthalocyanines signicantly change their properties such as absorption behavior and solubility. 9,[18][19][20][21][22][23] According to the positions of the substituents, it is readily understood that two different tetrasubstituted phthalocyanines differ signicantly in their photophysical and photochemical behaviors. Similarly, metal atoms coordinated to the phthalocyanine center are known to alter the electrochemical properties of the compound.…”

Comparative Studies of Photophysicochemical Properties of Non-Peripherally Anisole/Thioanisole-Tetrasubstituted Gallium (III) Phthalocyanines Containing Oxygen/ Sulfur Bridge

“…shows that the fluorescence excitation spectrum is blue-shifted by about 10 nm relative to that of the absorption spectrum, suggesting a change in geometry upon excitation (20) and 7). In every substituent, the complex showed similar quantum yields.…”

“…(methylthio)phenylthio))phthalocyaninatogallium(III) chloride (6) were prepared according to the procedures in literature (4,19,20). Some chemicals such as dimethyl sulfoxide (DMSO) and GaCl3 were acquired from Merck and Alfa Aesar and used as received.…”
