| Abstract: | The radical signal of two-photon initiated photopolymerization(TPIP) was captured in site firstly by means of electron spin resnance spectroscopy(ESR) technique and N-tert-butyl-α-phenylnitrone(BPN) captor, and the experimental results clear verify that the reaction of TPIP is radical mechanism. That one/two-photon fluorescence of the initiator can be quenched by monomers. The results show that there is energy transfer between initiator and monomer. Furthermore alone BDBAS can not give radical signal, thus we believe that this energy transfer is very important for producing radicals. |
