2-(4-Methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5-triazine Usage And Synthesis

Uses

Cationic photoinitiator. Nonionic photoacid generator.

Properties and Applications

2-(4-Methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5-triazine (R–Cl) appears as a versatile high-performance photoinitiator (PI) under LED exposure at 385, 395, or 405 nm (intensities in the range ～9–140 mW cm?2). It can be used as an efficient Type I cleavable photoinitiator for free radical polymerization of (meth)acrylates upon LED (e.g., 405 nm) exposure. Its high FRP photoinitiation ability under air demonstrates its capability to reduce the oxygen inhibition effect. Moreover, the R–Cl/amine (or R–Cl/N-vinylcarbazole) two-component system exhibits a higher photoinitiation ability than R–Cl alone in some cases. R–Cl/Iod/NVK is also efficient for the cationic photopolymerization of epoxides, especially at 405 nm[1].
