Photoreduction of 9,10-Phenanthrenequinone in the Presence of Dimethacrylate Oligomers and Their Polymers
2018
The effective rate constants for the photoreduction (kH) of 9,10-phenanthrenequinone (PQ) in the presence of dimethacrylate monomers (ethylene glycol dimethacrylate (DMEG), triethylene glycol dimethacrylate (TGM-3), and oligocarbonate dimethacrylate (OKM-2)) and porous polymers based on them have been spectrophotometrically determined. The values of kH in the presence of DMEG and TGM-3 in benzene solutions and in the monomer media are two times greater than in the presence of OKM-2. The values of kH for PQ in pores of polyDMEG, polyTGM-3, and polyOKM-2 are approximately identical and do not depend on the pore size (up to hundreds of nanometers) and the specific surface area.
