In 2021,Materials Chemistry Frontiers included an article by Luo, Dong; Zuo, Tao; Zheng, Ji; Long, Zi-Hao; Wang, Xue-Zhi; Huang, Yong-Liang; Zhou, Xiao-Ping; Li, Dan. Name: 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine. The article was titled 《Enabling photocatalytic activity of [Ru(2,2′:6′,2′′-terpyridine)2]2+ integrated into a metal-organic framework》. The information in the text is summarized as follows:
As a creation platform for multifunctional materials, crystalline metal-organic frameworks (MOFs) can integrate different chromophores through reticular chem. to adjust their spatial arrangement and intermol. interaction, in turn achieving the purpose of improving the nature of optoelectronic properties. Herein, a stepwise reticular synthesis approach is successfully used to construct a multicomponent MOF, in which the well-known bis-terpyridyl ruthenium chromophore is orderly arranged into the skeleton of the material. Remarkably, this method promotes the excited state lifetime of the bis-terpyridyl ruthenium core, by two orders of magnitude (from 0.39 to 22.09 ns), to the extent that it can produce singlet oxygen under visible light irradiation at room temperature Meanwhile, the obtained multicomponent MOF has been established to have considerable porosity for exposure of substrates to the catalytic sites, rendering it suitable for heterogeneous photocatalysis, including as a photooxidation detoxifier for sulfur mustard simulant. Moreover, DFT and TDDFT calculations reveal that the synergistic charge transfer among different components in the MOF may play a crucial role in improving the excited state properties of the bis-terpyridyl ruthenium motif. After reading the article, we found that the author used 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Name: 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine)
