Two-dimensionalcovalentorganicframeworks (2D-COFs) are a class of crystalline porous organic polymers that consist of covalently linked, two-dimensional sheets that can stack together through noncovalent interactions. Here we report the synthesis of a novel COF, called PyCOFamide, which has an experimentally observed pore size that is greater than 6 nm in diameter. This is among the largest pore

The present invention relates to a method for preparing a covalent organic framework (COF) materials - a reversible polycondensation/termination method, the COF materials prepared by the method have high crystallinity, high specific surface area, regular and controllable morphology. The present invention also relates to a method for repairing defects of COF materials - reversible degradation-recombination, the method can eliminate defects of existing COF materials, thereby increasing the crystallinity and specific surface area of COF materials and improving their morphological characteristics.
The present invention relates to sorbants such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), porous aromatic frameworks (PAFs) or porous polymer networks (PPNs) for separations of gases or liquids, gas storage, cooling, and heating applications, including, but not limited to, adsorption chillers.

The invention provides a polymer system, including a first composition and a second composition. The first composition is different from the second composition. The first composition includes a first gelator, the first gelator including a plurality of acylhydrazine moieties. The second composition includes a second gelator, the second gelator including a plurality of formyl moieties. At least one of the first composition and the second composition includes a prepolymer. The invention further provides a method of using the polymer system to form a polymeric material via multiple stages to more effectively control the rheology of the components over a variety of timescales.
