VINYL MONOMERS BEARING CHROMOPHORE MOIETIES AND THEIR POLYMERS——Ⅹ.INITIATION AND PHOTOCHEMICAL PROPERTIES OF p-(N,N-DIMETHYLAMINO)STYRENE AND ITS POLYMERS*
摘要:
A vinyl monomer having an electron-donating moiety, p-(N,N-dimethylamino)styrenc (DMAS),was synthesized. It was combined with benzoyl peroxide (BPO) to form a redox initiation system to initiatethe polymerization of methyl methacrylate (MMA). UV spectra measurements show that DMAS enters thePMMA chain as well. Both DMAS and its polymer P(DMAS) display strong fluorescence, and thefluorescence can be quenched by electron-deficient compounds such as methacrylonitrile, fumaronitrile and ethyl methacrylate etc.Moreover,DMAS can also form charge transfer complex (CTC) with strong electron acceptors such as tetracyanoethylene (TCNE).The difference between the photochemical properties of DMAS and P(DMAS) were explained in terms of molecular structure change and polymer conformation effect in solution.In addition,the CTC and exciplex formation of DMAS or P(DMAS) with C60 were also studied.
