Crystalline fibres of a covalent organic framework through bottom-up microfluidic synthesis

Abstract: A microfluidic chip has been used to prepare fibres of a porous polymer with high structural order, setting a precedent for the generation of a wide variety of materials using this reagent mixing approach that provides unique materials not accessible easily through bulk processes. The reaction between 1,3,5-tris(4-aminophenyl)benzene and 1,3,5-benzenetricarbaldehyde in acetic acid under continuous microfluidic flow conditions leads to the formation of a highly crystalline and porous covalent organic framework … Show more

“…[198] Such tandem approaches could enhance the scope of COF precursors with otherwise limited solubilities and stabilities.A cid-free procedures have been developed for precursors containing labile functional groups such as metalloporphyrins. [199] Microwave-assisted [200][201][202] and sonochemical [203] syntheses as well as organic terracotta processes [204] resulted in significantly faster reactions at lower temperatures.M echanochemical approaches allowed the room-temperature and solvent-free synthesis of iminebased COFs by either manual grinding or ball milling, [205] and COF synthesis in continuous flow devices [206,207] was also reported.…”
