ATRP ile ftalosiyanin içeren polimetilmetakrilat sentezi

Since their accidental discovery in 1930s, the phthalocyanines have been one of the most studied classes of organic functional materials because of their unusual chemical and physical properties Their diverse functionality comes from its 18-π electron aromatic system and their ability to coordinate with most of the metal atoms in the periodic table.Phthalocyanines can be incorprated whitin the the macromolecular structure as either network, main-chain or sidechain polymers. In addition, they can also be present as end-groups, pendant groups or as a core of a polymer which is an active area of research. ATRP is one of the very versatile and convenient techniques for polymer synthesis with good control of the molecular weight and relatively low polydispersities. ATRP also allows the synthesis of a variety of polymers with well-defined compositions, architectures, functionalities, and chain topology.In this study, methyl methacrylate is polymerized by ATRP using brominated phthalocyanines as macroinitiator. Therefore, hydroxy end group containing phthalocyanines are brominated to form reactive bromine groups. Structure of the phthalocyanines were examined by NMR, FT-IR and electrochemical studies. Bromine functional group take part in initiating the poly(methyl methacrylate) chain growth. Polymerization characteristics, chemical structure, thermal, UV-Vis, fluoresence and transmittance properties were examined by analysis.
