Benzothiazine Dyes/2,4,6-Tris(trichloromethyl)-1,3,5-triazine as a New Visible Two-Component Photoinitiator System
Figure 1
Electronic absorption spectra obtained on oxidation of 1 (saturated solution, <0.01 M) embedded in a BMIM+ : CH2Cl2 (1 : 1) matrix. (A) spectra were collected after radiolysis at 77 K (a) and after annealing of the matrix at 140 K for 5 min (b) and for 15 min (c). (B) After annealing at 140 K for 25 min (a) and at 150 K for 10 min (b) and 20 min (c). The sample was 2 mm thick and received a radiation dose of 7.2 kGy.
