“…These synthesismethods do not provide arational and universal way of preparing LnMOF nanothermometers, in particular,they are not amenable to scaling-up. Ar ecent collaboration between the groups of Rocha and Carlos, and Maspoch, provided an answer to this challenge by resorting to spray-drying synthesis, extending the methodf rom transition metals [51,52] to lanthanides. [29] In the spray-drying synthesis, the reaction mediumi sa tomized into droplets and Ln-MOFsn anoparticles form during the drying process and self-assemble into superstructures within the droplets, which act as individual reactors confining the growth of the crystals ( Figure 5).…”

“…Schoenecker et al [78] in 2013 reported a continuous process for the synthesis of UiO-66 using their patented reactor that uses batch technology with an integrated flow system to allow for the removal of products and introduction of reagents in situ. The Serre research group described a scalable aerosol system, which uses two liquid reagent streams injected into a flow of hot air, for the synthesis of HKUST-1, ZIF-8 and Fe 3 (BTC) 2 [79]. A similar spray-drying technique was also demonstrated by Carné-Sánchez et al [80].…”

As nanotechnology becomes increasingly important and ubiquitous, new and scalable synthetic approaches are needed to meet the growing demand for industrially viable routes to nanomaterial production. Continuous-flow hydrothermal synthesis or supercritical water hydrothermal synthesis (scWHS) is emerging as a versatile solution to this problem. The process was initially developed to take advantage of the tunable chemical and physical properties of superheated water to produce metal oxide nanoparticles by rapid nucleation and precipitation. The development of new mixing regimes and reactor designs has been facilitated by the modelling of reactor systems. These new reactor designs further exploit the properties of supercritical water to promote faster and more uniform mixing of reagent streams. The synthetic approach has been expanded beyond the metal oxide systems for which it was conceived, and now encompasses metal sulfides, metal phosphates, metal nanoparticles and metal-organic frameworks. In many of these cases, some degree of size and shape control can be achieved through careful consideration of both chemistry and reactor design. This review briefly considers the development of scWHS reactor technology, before highlighting some of our recent work in expanding the scope of this synthetic method to include a wide range of materials.

“…One solution to the problems encountered in liquid/liquid MOF synthesis is to perform self‐assembly at liquid/air interfaces generated in an aerosol, as one can use the same mixtures as those used in solvothermal synthesis 43. 44 In fact, our group has synthesised a wide range of hollow MOF superstructures by exploiting the special conditions that dictate precipitation and reaction during the drying of an aerosol droplet (see Figure 6 f). 43 This spray‐drying method does not require any additional immiscible solvents, surfactants, emulsifiers or agitation (e.g., stirring or sonication).…”

Metal-organic frameworks (MOFs) are among the most attractive porous materials known today, exhibiting very high surface areas, tuneable pore sizes and shapes, adjustable surface functionality, and flexible structures. Advances in the formation of MOF crystals, and in their subsequent assembly into more complex and/or composite superstructures, should expand the scope of these materials in many applications (e.g., drug delivery, chemical sensors, selective reactors and removal devices, etc.) and facilitate their integration onto surfaces and into devices. This Concept article aims to showcase recently developed synthetic strategies to control the one-, two- and three-dimensional (1-, 2- and 3D) organisation of MOF crystals.
