However, the lack of solvent-free and easy-to-perform synthesis processes appears to be the bottleneck toward their greener fabrication, thereby limiting their possible potential applications. To alleviate such shortcomings, we demonstrate a simple route toward the rapid synthesis of highly crystalline and ultraporous COFs in seconds using a novel salt-mediated crystallization approach. A high degree of synthetic control in interlayer stacking and layer planarity renders an ordered network with a surface area as high as 3000 m(2) g-(1). Further, this approach has been extrapolated for the continuous synthesis of COFs by means of a twin screw extruder and in situ processes of COFs into different shapes mimicking the ancient terracotta process. Finally, the regular COF beads are shown to outperform the leading zeolites in water sorption performance, with notably facile regeneration ability and structural integrity.</p>1 aKarak, S.1 aKandambeth, S.1 aBiswal, B., P.1 aSasmal, H., S.1 aKumar, S.1 aPachfule, P.1 aBanerjee, R.  uhttp://library.ncl.res.in/content/constructing-ultraporous-covalent-organic-fameworks-seconds-organic-terracotta-process01284nas a2200157   4500008004100000245006400041210006300105260000800168300001600176490000900192520078400201100001900985700001201004700001701016856009301033       2018                        eng d00aCovalent organic frameworks: chemistry beyond the structure0 aCovalent organic frameworks chemistry beyond the structure  cNOV  a1807–18220 v141 3 aCovalent organic frameworks (COFs) represent a new field of rapidly growing chemical research that takes direct inspiration from diverse covalent bonds existing between atoms. The success of linking atoms in two and three dimensions to construct extended framework structures moved the chemistry of COFs beyond the structures to methodologies, highlighting the possibility of prospective applications. Although structure to property relation in COFs has led to fascinating properties, chemical stability, processability and scalability were some of the important challenges that needed to be overcome for their successful implementation. In this Perspective, we take a closer look at the growth of COFs from mere supramolecular structures to potential industrializable materials.1 aKandambeth, S.1 aDey, K.1 aBanerjee, R.  uhttp://library.ncl.res.in/content/covalent-organic-frameworks-chemistry-beyond-structure
