Abstract:
Phthalocyanines are synthetic macrocyclic compounds which are used as dyestuff,photodynamic reagents for cancer therapy and for some other medical applications. Alsophthalocyanines have a great technological potential in areas related to intrinsicsemiconductors and nonlinear optics.Coumarin derivatives are an important class of natural compounds havingpharmaceutical activities. These compounds have many effects such as anticarcinogenecity,antifungal, anticoagulant and dispersed fluorescent.In this study, the synthesis of novel 4-hydroxyphenylacetic acid derivatives of metal-free phthalocyanines and metallophthalocyanines were performed. Also metal-freephthalocyanines and metallophthalocyanines containing coumarin moieties were performed.The structures of these new compounds were determined.First, p-(3,4-dicyanophenoxy)phenylacetic acid was synthesized. Metal-freephthalocyanine and metallophthalocyanines were performed by reaction of p-(3,4-dicyanophenoxy)phenylacetic acid and several metal salts in solvents which have highboiling point. Acid chlorides were prepared by reaction of thionylchloride andphthalocyanines containing carboxylic acid groups. Phthalocyanines containing amidmoieties were synthesized by reaction of benzylamine and acid chlorides in THF.Phthalocyanines containing esther moieties were synthesized by reaction of octanol andacid chlorides in pyridine. Phthalocyanin compounds were purified by extraction withseveral solvents.7-Octiloxy-3-[p-(3?,4?-dicyanophenoxy)phenyl]coumarin was synthesized by PerkinReaction. Metal-free phthalocyanine containing coumarin moieties was performed byreaction of 7-octiloxy-3-[p-(3?,4?-dicyanophenoxy)phenyl]coumarin in 2-dimethylaminoethanol. Zinc metallo phthalocyanine containing coumarin moieties wasperformed by reaction of 7-octiloxy-3-[p-(3?,4?-dicyanophenoxy)phenyl]- coumarin andZn(AcO)2.2H2O in 2-dimethylaminoethanol. The purification of phthalocyanines containingcoumarin moieties were made by using silica gel column chromatography.The structures of this new compounds were determined based on the results ofspectroscopic methods such as UV/VIS, FT-IR, 1H-NMR and 13C-NMR .Keywords: 4-Hydroxyphenylacetic acid, Phthalocyanine, Coumarin.May, 2005 Meryem ÇAMUR
