We present new highly microporous element organic frameworks synthesized by the Pd catalyzed Suzuki coupling reaction. They show specific surface areas of up to 1380 m 2 g À1 with a strong hydrophobic character. Thus, they are interesting for the adsorption of non-polar substances. By variation of the organic linkers, the modular concept of the materials in analogy to the metal-organic frameworks is demonstrated. The polymeric materials have thermal stability up to 573 K and show no decomposition in aqueous environment, allowing excellent handling and processing. They are accessible by a basic synthetic approach, and by their chemical and thermal stabilities they may provide adequate properties for applications in many fields, especially in adsorptive separation processes and storage of non-polar gases.
Metal-organic frameworks (MOFs) are well known for their outstanding sorption properties and therefore under consideration as new high performance adsorbents. [1] A lot of applications in different fields seem feasible. [2] Especially gas storage, [3] heterogeneous catalysis, [4] and separation/purification processes [5] are the fields under intense research and most mentioned in the literature. Describing exclusively the performance of the materials, only little attention is paid to the morphology and size of the particles, which is crucial for the different fields of applications. A few of the known MOF materials appear in form of small single crystals while often fine powders with particles on the lower micrometer scale are the product. For certain applications they have to be better processable. Methods under consideration, like pelletizing [6]
a Novel supported ionic liquid phase (SILP) gas purification materials have been developed to remove ammonia irreversibly from an ambient gas flow of nitrogen (1000 ppm NH 3 in N 2 , wet and dry). In the applied SILP materials, thin films of imidazolium based ionic liquids and ionic solutions of metal com-
Polymer-based spherical activated carbon (PBSAC), produced by means of carbonization and subsequent activation of a polymeric precursor in a batch process represent adsorbents with adjustable pore size distribution and adsorption characteristics. This flexibility results from batch operation and from the possibility to combine different activation media, therefore controlling the mechanisms of pore generation. The geometry and the mechanical properties of PBSAC allow for structuring of filter media e.g., for adsorbent enlargement or fixation. Other intrinsic product properties such as roundness, high crush strength and high abrasion resistance of PBSAC offer advantages in various adsorption applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
