Abstract:

Using epichlorohydrin as bridged unit, the aromatic tertiary amine (ATA) was introduced to prepare the highly photo-crosslinkable coumarin compound C and to accelerate the photo-dimerization of coumarin unit. Ultraviolet (UV) and fluorescence (FL) spectra were used to evaluate the coumarin C. It was found that the introduced ATA could enhance the absorption between 260-400 nm. The spot UV irradiation experiments showed that, after being bridged with ATA, the coumarin C would gain a highly photo-dimerization with a high slope of 6.47 in the uniform photo-reaction, and a short time of 29 s to gain 80% photo-dimerization.

Key words: Coumarin, Epichlorohydrin, Aromatic tertiary amine, Photo-induced, Photo-dimerization
