在点击化学上发光：除了提供在点击转化中实现正交性的进一步手段之外，使用UV辐射作为触发信号提供了一种容易的手段来获得对聚合物缀合反应的空间和时间控制。在目前的贡献中，紫外线辐射被用来诱导一个高效的Diels-Alder共轭的聚合物结构单元通过光诱导原位形成高反应性的顺式二烯从2-甲基二苯甲酮前体。
Shining a light on click chemistry: The use of UV-radiation as trigger signal provides a facile means to obtain spatial and temporal control over polymer conjugation reactions in addition to providing a further means of achieving orthogonality in click transformations. In the current contribution, UV-radiation was employed to induce a highly efficient Diels-Alder conjugation of polymeric building blocks via the photo-induced in situ formation of highly reactive cis-dienes from a 2-methylbenzophenone precursor.
