《Synthesis, characterization, and determination of photophysicochemical properties of peripheral and nonperipheral tetra-7-oxy-3,4-dimethylcoumarin substituted zinc, indium phthalocyanines》 was written by Artuc, Gamze Oezguel; Karapinar, Beguemhan; Oezdemir, Muecahit; Bulut, Mustafa. Computed Properties of C7H12O3This research focused onzinc indium tetraoxydimethylcoumarinylphthalocyanine complex preparation fluorescence lifetime photodynamic therapy. The article conveys some information:
The photochem. and photophys. properties of peripheral and nonperipheral zinc and indium phthalocyanines containing 7-oxy-3,4-dimethylcoumarin synthesized were investigated in this study. 7-Hydroxy-3,4-dimethylcoumarin (1) was synthesized via Pechmann condensation reaction and then the phthalonitrile derivatives [4-(7-oxy-3,4-dimethylcoumarino)phthalonitrile (2) and 3-(7-oxy-3,4-dimethylcoumarino)phthalonitrile (3)] were synthesized by nucleophilic aromatic substitution. Phthalocyanine compounds containing coumarin units on peripheral (4 and 5) and nonperipheral (6 and 7) positions were prepared via cyclotetramerization of phthalonitrile compounds All compounds’ characterizations were performed by spectroscopic methods and elemental anal. The phthalocyanine derivatives (4-7) photochem. and photophys. properties were studied in DMF. The photophys. (fluorescence quantum yields and lifetimes) and photochem. (singlet oxygen and photodegradation quantum yields) properties of these novel phthalocyanines (4-7) were studied in DMF. They produced good singlet oxygen (e.g., ΦΔ = 0.93 for 7) and showed appropriate photodegradation (in the order of 10-5), which is very important for photodynamic therapy applications. The experimental process involved the reaction of Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3Computed Properties of C7H12O3)
Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Computed Properties of C7H12O3
