Porfirin içeren polimerler

In this thesis, porphyrin-derived polymers were synthesized and characterized. Porphyrins are heteromacrocyclic structures that result from the attachment of four pyrrole rings by a methylene bridge. They can be obtained in laboratory conditions as well as in nature. The optical properties of these compounds are theoretically and spectroscopically applied, and the porphyrin is the target material in this field. In addition, porphyrin compounds have strong fluorescence properties because they are conjugated 18 π-electron systems. Because of these properties, today polymers containing porphyrin compounds are used in photochemistry, solar cells, optical sensor, photodynamic therapy, etc. It is widely used in the fields. In this work, tetraphenylporphyrin compound was first synthesized by the condensation reaction of pyrrole and benzaldehyde, then the synthesized compound was nitrated. Nitro-functional porphyrin compound is reduced to amine. The amine-functional porphyrin compound enters the esterification reaction with methacryloyl chloride compound and is converted to a polymerizable species by radical method involving porphyrin. Copolymer was synthesized with obtained porphyrin functional monomer and styrene by free radical polymerization method. Characterization studies of porphyrin-containing copolymers were supported by FTIR, H1-NMR and Uv-Visible Spectroscopy. The molecular weight of the polymer was determined by gel permeation chromatography. Thermal analyzes of monomers and polymers were carried out by thermogravimetric analysis.
