One pot synthesis and characterization of hyperbranched copolymers photochemically converted to linear copolymers

Anthracene compound undergoes a coupling reaction with photochemically changing under the UV visible light ( >350 nm) and it dimerizes with another anthracene molecule. Resulting the dimer molecule is able to easily seperate each other under the UVC light (<254 nm). In this project, hyperbranched copolymers were synthesized in one pot reaction procedure using with photochemically dimerization of anthracene molecules in the presence of monomeric anthracene, methyl methacrylate and Irgacure 184 as a photoinitiator under the UV visible light. Obtained various hyperbranched copolymers were transformed into the linear copolymers under the UV visible light irradiation. Molecular weights, thermal and photophysical properties of dimerized hyperbranched and linear copolymers were invastigated and characterized.
