Abstract

Zinc porphyrin single-site was prepared by encapsulating the negatively charged porphyrin within a tetraprismatic molecular cage (Mcage). Elemental analysis, ¹H NMR titration, absorption spectra and Job plots confirmed that each Mcage encapsulated only one porphyrin molecule to produce the Mcage-porphyrin hybrids, which acted as both light-sensitizer and single-site photocatalyst for aerobic oxidation of aromatic thioethers to sulfoxides with an excellent selectivity under visible light irradiation.

在四棱镜分子笼内包封卟啉锌作为高效光敏剂和单位点光催化剂

将带负电荷的卟啉包封在四棱镜分子笼中制备单位点锌卟啉。元素分析、1H NMR滴定、吸收光谱和Job图证实，每个Mcage只包封一个卟啉分子就能生成Mcage-卟啉杂化物，该杂化物在可见光照射下作为芳香硫醚有氧氧化制亚砜的光敏剂和单位点光催化剂，具有良好的选择性。
