Anthracene derivatives with several TEMPO radicals (2-4, 10) were prepared, and each photodimerization reaction was investigated. Although the photodimerization was unsuccessful in obtaining the dimers of anthracenes 2 and 3, which could be alternatively prepared in a stepwise manner, the photodimers of anthracenes 4 and 10 were available by the direct photoreaction. The dissociation reaction of the
制备具有几个TEMPO自由基(2-4、10)的蒽衍生物,并研究每个光二聚反应。尽管光二聚化不能成功地获得蒽2和3的二聚体,其可以以逐步方式制备,但是蒽4和10的光二聚体可通过直接光反应获得。通过在溶液中加热二聚体以分别得到相应的单体,使二聚体的解离反应进行得很好,因此在后两个体系中可以构建可逆体系。虽然在4和8的单体/二聚体对之间没有观察到很大的磁行为差异。
