Incorporation of a dioxo-molybdenum (VI) complex into a titanium-functionalized Zr(IV)-Based metal-organic framework

An electroactive metal–organic framework-based novel on–off ratiometric electrochemical platform for effective detection of lead ions

“…For the O 1s spectrum of GO/UiO-bpy, three subbands at 532.9 eV, 531.5 eV and 529.9 eV are deconvoluted into peaks corresponding to C–O, CO and O–metal, respectively. 30,31 After adsorption of Pb 2+ , the relative content of O–metal increases from 11.4% for GO/UiO-bpy to 13.0% for GO/UiO-bpy-Pb-1 and 22.9% for GO/UiO-bpy-Pb-2. This illustrates that O–Pb coordination may also occur in GO/UiO-bpy-Pb-1 and GO/UiO-bpy-Pb-2.…”

“…The peaks appearing at 1687 cm −1 and 1425 cm −1 are attributed to carboxylate vibrations. 30 Aer Pb 2+ was adsorbed by GO/UiO-bpy, the characteristic peak of pyridine rings (C]N) moves from 1594 cm −1 to 1598 cm −1 . At the same time, a peak at 532 cm −1 appears, which corresponds to the stretching vibration of O-Pb.…”

Postsynthetic Modification of Metal−Organic Frameworks for Photocatalytic Applications

“…Thus, 2,2 0 -bipyridine-derived MOFs provide a potential path to build functional MOFs for photocatalysis by postmodification, because the photoexcited electrons from ligands could be transferred efficiently to metal active sites. [2,[70][71][72][73][74][75][76][77][78] Xu and co-workers reported a bifunctional MOF-253-Pt through immobilizing a platinum complex in MOF-253 by the coordination of 2,2,-bipyridine chelating ligands to platinum ions. The functionalized MOF-253-Pt acts as not only a photosensitizer but also a water-splitting catalyst.…”

Study on the Selective Hydrogenation of Quinoline Catalyzed by Composites of Metal-Organic Framework and Pt Nanoparticles※

“…). 相比于 UiO-67, UiO-67N 在 1365.87 cm -1 处显 示出一个明显的特征峰, 这主要是来自于联吡啶环相关 的振动峰 [44] . 喹啉在 1370.86 cm -1 处显示出了一个特征 峰, 根据文献 [45]的报道, 可以推测为吡啶环的变形振 动峰.…”
