Core-crosslinked star polymers, which have polyethylene oxide (PEO) as a shell and cross-linked poly(2-{4′-iodobenzoyloxy}-Et methacrylate) (PIEMA) with benzophenone derivatives as a core, have been successfully synthesized by an “”arm-first”” method. PEO-b-PIEMA was prepared via atom transfer radical polymerization (ATRP) of 2-{4′-iodobenzoyloxy}-Et methacrylate (4-IEMA) with preformed PEO-Br as a macroinitiator. Core-crosslinked star polymers (CCSP) were efficiently synthesized by ultrafast carbonylation reactions under air by flash microwave irradiation in the presence of dicobalt octacarbonyl in 6 min. Gel permeation chromatog. (GPC) trace of CCSP showed a drastic shift to a higher mol. weight when compared to precursor polymer, PEO-b-PIEMA diblock copolymer, indicating that the carbonylation reaction was fully progressed. The CCSP with benzophenone was successfully immobilized on a silicon wafer through a photochem. reaction under UV irradiation The results came from multiple reactions, including the reaction of 4-Iodobenzoic acid(cas: 619-58-9Recommanded Product: 4-Iodobenzoic acid)
4-Iodobenzoic acid(cas: 619-58-9) belongs to organic iodides.Recommanded Product: 4-Iodobenzoic acid The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.
