A one-step synthesis of a well-defined mid-chain functional macrophotoinitiator of polystyrene- poly(ɛ-caprolactone) diblock copolymer (PSt-PI-PCL) was successfully performed at 110 °C using a dual-functional photoinitiator via simultaneous ATRP and ROP. The new dual-functional photoinitiator (Br-PI-OH) possessing a bromine group on one end and a hydroxyl group on the other, was synthesized by reaction of Irgacure 2959 photoinitiator (HO-PI-OH) with 2-bromopropanoyl bromide. The two distinct polymerization reactions proceeded in a controlled manner without mutual interference. Elemental analysis and 1H-NMR, 13C-NMR and Fourier transform infrared spectroscopy (FT-IR) spectroscopy were used to characterize the chemical structure of Br-PI-OH. Characterization of the macrophotoinitiator PSt-PI-PCL was achieved using 1H-NMR, FT-IR, gel permeation chromatography, UV-vis and fluorescence spectroscopy.
