Hierarchical Assembly of a Micro‐ and Macroporous Hydrogen‐Bonded Organic Framework with Tailored Single‐Crystal Size

Porous organic molecular materials represent an emergent field of research in Chemistry and Materials Science due to their unique combination properties. To enhance performance expand the number applications, incorporation hierarchical porosity is required, as exclusive microporosity entails several limitations. However, integration macropores porous still outstanding challenge. Herein, we report first example a hydrogen-bonded framework (MM-TPY) with skeletal morphology, containing stable micro- macroporosity. The crystal size, from micro centimetre scale, can be controlled single step without using additives or templates. mechanism assembly during formation compatible growth. As proof concept, employed platform for dual, sequential selective co-recognition species microparticles.
