Zinc(II) and Copper(II) Metal–Organic Frameworks Constructed from a Terphenyl-4,4′′-dicarboxylic Acid Derivative: Synthesis, Structure, and Catalytic Application in the Cyanosilylation of Aldehydes

Solvothermal reaction of zinc(II) and copper(II) salts with 3,3′′-dipropoxy-[1,1′:4′,1′′-terphenyl]-4,4′′-dicarboxylic acid (H2L) gave rise to the 1D and 2D metal–organic frameworks (MOFs) [Zn(L)(dmf)2]n(1), [Zn2/sub

Rapid, Scalable Construction of Highly Crystalline Acylhydrazone Two-Dimensional Covalent Organic Frameworks via Dipole-Induced Antiparallel Stacking

Covalent organic frameworks are an emerging class of porous crystalline organic materials that can be designed and synthesized from the bottom up. Despite progress made in synthesizing COFs of diverse topologies, the synthesis methods are often tedious and unscalable, hampering practical applications. Herein, we demonstrate a scalable, robust method of producing highly crystalline acylhydrazone two-dimensional (2D) COFs with diversified structures (six examples) under open and stirred conditions, with growth typically completed in only 30 min. Our strategy involves selecting molecular building blocks that have bond dipole moments with spatial orientations that favor antiparallel stacking and whose structure allows the restriction of intramolecular bond rotation (RIR) via intra- A nd interlayer hydrogen bonding. This method is widely applicable for hydrazide linkers containing various side-chain functionalities and topicities. By this strategy, the gram-scale synthesis of two highly crystalline COFs (up to 1.4 g yield) was obtained in a one-pot reaction within 30 min.

COVALENT ORGANIC FRAMEWORK AND METHODS OF FABRICATION AND USES THEREOF

The present invention relates to, in general, methods of fabricating a covalent organic framework (COF) and the COF thereof. In particular, the method comprises forming an acylhydrazone bond with an optionally substituted 2-alkoxybenzohydrazidyl moiety. The resultant COF has an x-ray diffraction 2-theta peak at about 3? with a full width half maximum (FWHM) of about 0.2? to about 0.4?.
