摘要：

Household LED bulbs are used to promote the ring-opening photopolymerization of epoxides in the presence of a photocatalyst (here tris(2-phenylpyridine)iridium [Ir(ppy)(3)] or tris(1,10-phenanthroline)ruthenium(II) [Ru(phen) (3) (2+) ] complex) and a silyl radical source. Remarkably, even under this very soft irradiation (light intensity lower than 10 mW/cmA(2)), excellent polymerization profiles are obtained i.e., this is the first reported use of such very convenient irradiation devices for photopolymerization processes. The role of the silane and other hydrogen donors is outlined.
