Abstract Controlling the shape of metal–organic framework (MOF) crystals is important for understanding their crystallization and useful myriad applications. However, despite many advances in shaping inorganic nanoparticles, post‐synthetic control MOFs and, general, molecular remains embryonic. Herein, we report using a simple wet‐chemistry process at room temperature to anisotropic etching colloidal ZIF‐8 ZIF‐67 crystals. Our work enables uniform reshaping these porous materials into...
Accurate, noninvasive, and self‐referenced temperature measurements at the submicrometer scale are of great interest, prompted by ever‐growing demands in fields nanotechnology nanomedicine. The thermal dependence phosphor's luminescence provides high detection sensitivity spatial resolution with short acquisition times in, e.g., biological fluids, strong electromagnetic fields, fast‐moving objects. Here, it is shown that nanoparticles [(Tb 0.914 Eu 0.086 ) 2 (PDA) 3 (H O)]·2H O (PDA =...
Metal-organic frameworks (MOFs) are among the most attractive porous materials available today. They have garnered much attention for their potential utility in many different areas such as gas storage, separation, catalysis, and biomedicine. However, very little is known about possible health or environmental risks of these materials. Here, results toxicity studies on sixteen representative uncoated MOF nanoparticles (nanoMOFs), which were assessed cytotoxicity to HepG2 MCF7 cells vitro,...
Abstract The use of covalent organic frameworks (COFs) in practical applications demands shaping them into macroscopic objects, which remains challenging. Herein, we report a simple three‐step method to produce COF aerogels, based on sol‐gel transition, solvent‐exchange, and supercritical CO 2 drying, 2D imine‐based sheets link together form hierarchical porous structures. resultant aerogel monoliths have extremely low densities (ca. 0.02 g cm −3 ), high porosity (total values ca. 99 %),...
Spray-drying is a popular and well-known "drying tool" for engineers. This perspective highlights that, beyond this application, spray-drying very interesting powerful tool materials chemists to enable the design of multifunctional hybrid materials. Upon spray-drying, confined space liquid droplet narrowed down, its ingredients are forced together upon "falling dry." As detailed in article, enables following material formation strategies either individually or even combination: nanoparticles...
Micro- and nanoscale coordination polymer particles can be used for encapsulating delivering drugs. In vitro cancer cell cytotoxicity assays showed that these capsules readily release doxorubicin, which shows anticancer efficacy. The results from this work open up new avenues metal–organic to as potential drug delivery systems.
Music of the spheres: Infinite coordination polymerization Zn(2+) ions and a multitopic ligand produces metal-organic micro- nanospheres that can be used as functional matrices. The spheres encapsulate combinations active substances, such organic dyes, magnetic nanoparticles, or luminescent quantum dots (see image), which results in are blue, green, red regions spectrum.
Metal–organic nanoparticles (see SEM image) showing valence-tautomeric behavior have been obtained by a versatile approach involving precipitation and coordination polymerization. They undergo reversible temperature-dependent interconversion between low- high-spin forms, as revealed plotting the magnetic moment χ function of temperature.

Adsorptive heat transformation systems such as adsorption thermal batteries and chillers can provide space heating cooling in a more environmental friendly way. However, their use is still hindered by relatively poor performances large sizes due to the limited properties of solid adsorbents.

Many metal-organic frameworks are water labile, including the iconic Hong-Kong University of Science and Technology-1 (HKUST-1). Spray-dry encapsulation HKUST-1 crystals into polystyrene microspheres is reported here to yield composites that resistant but retain most excellent gas sorption capacity HKUST-1.

Herein we report a novel, ozone-based method for postsynthetic generation of mesoporosity in metal–organic frameworks (MOFs). By carefully selecting mixed-ligand Zr-fcu-MOFs based on organic ligand pairs which one has ozone-cleavable olefin bonds and the other is ozone-resistant, were able to selectively break cleavable via ozonolysis trigger fusion micropores into mesopores within MOF framework. This solid–gas phase performed at room-temperature, and, depending used, resultant...
