| 摘 要： | 以环氧氯丙烷为桥接, 将具有较强给电子能力的芳叔胺(ATA)结构引入香豆素衍生物C分子中, 通过芳叔胺结构的光化学促进作用加速香豆素基元的光二聚反应. 用紫外(UV)和荧光(FL)光谱等手段对该香豆素衍生物进行表征. 结果表明, 芳叔胺结构的引入可有效增强香豆素基元在260-400 nm之间的吸收. 紫外点光源光二聚反应实验表明, 芳叔胺结构的引入使香豆素基元的光响应性能得以大幅增强, 在相同光照条件下, 其在匀速反应区间内对光照时间的依赖性的斜率高达6.47, 光二聚反应程度达到80%时所需光照时间仅为29 s.

| 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. |
