Sažetak
Hydrogen-bonded organic frameworks (HOFs) are polymeric supramolecular assemblies of organic molecules held together by hydrogen bonds. They are an emerging class of lightweight and metal- free functional materials that show promise in gas storage, separation, catalysis, and biomedical applications. Importantly, HOF guest accommodation properties are dependent on their specific polymorphic forms. Here, we present the case of 2, 6-diaminopurine (DAP), whose commercial bulk chemical is a mixture of two crystalline phases. Solid form screening resulted in five new DAP solid forms with a new DAP HOF polymorph. Two DAP HOF polymorphs were synthesized selectively by choosing the liquid additive in liquid-assisted grinding (LAG) and showed different reaction profiles as monitored by in situ Raman spectroscopy. Our results represent the first mechanochemical synthesis of HOFs, demonstrate the ability to control their polymorphism, and open more sustainable synthetic routes towards these functional materials.
