The incorporation of photoactive donor-acceptor Stenhouse adduct (DASA) moieties into Metal-Organic Frameworks (MOFs) provides a new route to the development of visible light switching materials. Herein, a DUT-5 mixed-linker defect series was exploited to produce a derivative group of DASA-modified materials via postsynthetic modification (PSM). The photoactive MOFs exhibited conversion stimulated by visible wavelengths and were stable following multiple cycles. Thermodynamic and metastable states persisted over an extended time period.
将光活性供体-受体斯滕豪斯加合物（DASA）部分引入金属有机框架（MOF）中，为开发可见光开关材料提供了一条新途径。在此，利用DUT-5混合连接体缺陷系列，通过后合成修饰（PSM）制备了一组DASA修饰材料的衍生物。这些光活性MOF在可见光波长激发下表现出转换现象，并且在多次循环后仍保持稳定。热力学和亚稳态在较长时间内持续存在。
