A Recyclable Metal–Organic Framework as a Dual Detector and Adsorbent for Ammonia

Sonochemical synthesis of a trinuclear Cu(ii) complex with open coordination sites for the differentiable optical detection of volatile amines

“…S2 †) reveals a broad peak in the 3000-3500 cm À1 region, which is attributed to the stretching vibrations of the N-H and O-H groups from dpyam and water molecules, respectively. [39][40][41] The medium peak at about 1640 cm À1 is attributed to the stretching vibration of the pyridine ring. 42,43 The peaks at approximately 1600-1400 cm À1 are ascribed to the asymmetric and symmetric stretching vibrations of the carboxylate group for the pzdc ligand.…”

High Ammonia Uptake of a Metal–Organic Framework Adsorbent in a Wide Pressure Range

“…[22] Some MOFs and composite materials showed significant wet capacities but their structural stabilities and recyclability remained unexplored. [22,43,44] It is undeniable that Mg 2 (dobpdc) is au nique example that is recyclable even in humid NH 3 streams without experiencing structural degradation or capacity loss. + at 1417 cm À1 .d )Time variation of the peak ratio at 1625 cm À1 ,1 140 cm À1 ,a nd 1417 cm À1 under ambient conditions after NH 3 adsorption.…”

Composite Materials Manufactured by Photopolymer 3D Printing with Metal-Organic Frameworks

“…Metal-organic frameworks (MOFs) [1] possess a number of unique properties (first of all, low density and high porosity [2]) and, hence, they are actively used for gas storage [3] and separation [4] and as materials for nonlinear optics [5], sensorics [6], magnetism [7], medicinal chemistry [8], and catalysis [9]. Despite the wide variety of MOF-based catalysts, virtually each of them can be classified into one of three types, in which the catalytic site is (a) located on the metal ion in the metal-containing unit, (b) bound to an organic linker, or (c) encapsulated inside the pores.…”
