Abstract：

The　use　mesoporous　graphitic　carbon　nitride　(mpg-C3N　4)　in　conjunction　with　tertiary　amines　as　initiators　in　visible-light-induced　free　radical　polymerization　is　described.　The　initiation　mechanism　involves　photoinduced　free　radical　generation　by　scavenging　holes　with　amines　and　subsequent　hydrogen　abstraction.　The　efficiency　of　the　photoinitiation　is　controlled　by　the　nature　of　the　amines　and　specific　surface　area　of　the　carbon　nitride　powder.　Apparently,　amines　with　higher　basicity　and　available　hydrogens　provide　more　favorable　conditions　for　the　photoinitiation　process.　Due　to　its　heterogeneous　nature,　the　photoinitiator　preserves　its　photoinitiation　activity　after　the　polymerization　and　can　easily　be　separated　and　used　for　further　polymerizations.　(Figure　presented)　©　2012　American　Chemical　Society.
