In this study, we report the successful incorporation of the photoactive bis(4'-(4-carboxyphenyl)-terpyridine)ruthenium(II) (Ru(cptpy)) strut into a robust metal-organic framework (MOF), AUBM-4. The single crystal X-ray analysis revealed the formation of a new one-dimensional structure of Ru(cptpy) complexes linked together by Zr atoms that are eight coordinated with O atoms. The chemically stable MOF structure was employed as an efficient photocatalyst for carbon dioxide conversion to formate under visible light irradiation. To the best of our knowledge, the obtained conversion rate is among the highest reported in the literature for similar systems. Our strategy of using the Ru(cptpy) complex as a linker to construct the MOF catalyst appears to be very promising in artificial photosynthesis.
在本研究中，我们报告了将光活性双（4'-（4-羧基苯基）-三联吡啶）钌（II）（Ru（cptpy））支柱成功整合到坚固的金属有机框架（MOF）AUBM-4中。单晶X射线分析揭示了由与O原子八配位的Zr原子连接在一起的Ru（cptpy）配合物形成了一种新的一维结构。化学稳定的MOF结构被用作在可见光照射下将二氧化碳转化为甲酸盐的高效光催化剂。据我们所知，所获得的转化率是文献中报道的类似体系中最高的之一。我们使用Ru（cptpy）配合物作为连接体来构建MOF催化剂的策略在人工光合作用中似乎非常有前景。
