The utilization of reactive oxygen species (ROS) in photochemical synthesis has garnered significant attention owing to their exceptional oxidative capacity under mild conditions. Recently, metal-organic frameworks (MOFs) have been employed to transfer molecular oxygen (O2) to ROS for photocatalysis. However, visible-light-active MOFs for effective oxygen activation remains scarce. Herein, a simple and effective strategy, linker functionalization, was utilized to immobilize benzothiadiazole unit inside the UiO-68-type MOF (UiO-68-BTDB). The MOF was applied as the first example generating superoxide radical anion (O2•−) and singlet oxygen (1O2) for the access to benzimidazoles and benzothiazoles under ambient air at room temperature. Recycling experiments were performed to confirm the stability and reusability of UiO-68-BTDB as a robust heterogeneous catalyst

可见光活性苯并噻二唑基 MOF 作为高效 ROS 发生器用于合成苯并咪唑和苯并噻唑


活性氧（ROS）在光化学合成中的利用因其在温和条件下卓越的氧化能力而受到广泛关注。最近，金属有机框架（MOF）已被用来将分子氧（O2）转移到ROS以进行光催化。然而，用于有效氧活化的可见光活性 MOF 仍然很少。在此，利用一种简单而有效的策略，即连接基功能化，将苯并噻二唑单元固定在UiO-68型MOF（UiO-68-BTDB）内。 MOF 被用作第一个在室温下在环境空气中生成超氧自由基阴离子 (O2•−) 和单线态氧 (1O2) 的例子，以获取苯并咪唑和苯并噻唑。进行回收实验以确认 UiO-68-BTDB 作为稳健的多相催化剂的稳定性和可重复使用性
