Singlet oxygen donors are of current interest for medical applications, but suffer from a short half‐life leading to low singlet oxygen yields and problems with storage. We have synthesized more than 25 new singlet oxygen donors based on differently substituted naphthalenes in only a few steps. The influence of functional groups on the reaction rate of the photooxygenations, thermolysis, half‐life
单线态氧供体目前在医学上很受关注,但半衰期短,导致单线态氧产量低和储存问题。我们仅需几个步骤就可以合成25种以上基于不同取代萘的单线态氧供体。彻底研究了官能团对光氧合反应速率,热分解,半衰期和单线态氧产量的影响。我们确定了各种热力学数据,并将其与密度泛函计算进行了比较。有趣的是,已经发现在光氧化过程中官能团的显着稳定性以及在热分解过程中某些内过氧化物的稳定作用。此外,我们提供了部分协同作用和部分逐步热解机理分别导致单重态和三重态氧的证据。我们的结果可能对“黑暗的氧合”和未来在医学中的应用很有趣。
