Reticular synthesis of 8-connected carboxyl hydrogen-bonded organic frameworks for white-light-emission

Abstract

The rational design and construction of hydrogen-bonded organic frameworks (HOFs) are crucial for enabling their practical applications, but controlling their structure and preparation as intended remains challenging. Inspired by the...

Unravelling the photobehavior of a 2,1,3-benzothiadiazole-based HOF and its molecular units: experimental and theoretical insights into their spectroscopic properties in solution and in the solid state

“…In the last decade, HOFs have emerged as new porous materials with diverse possible applications, such as in gas storage and separation, catalysis, luminescent sensing, and optoelectronic devices. 10–12,16,18–23 HOFs are assembled from organic units through intermolecular hydrogen (H) bonding interactions, and the resulting frameworks can be further strengthened via other interactions, such as π–π stacking, van der Waals, dipole–dipole and/or C–H–π interactions. 11,12,17,24,25 The inherent features of H-bond interactions, such as reversibility and directionality, endow these materials with unique properties, including crystallinity, flexibility, structural diversity, and easy recovery via recrystallization.…”

“…These photoinduced reactions lead to significant changes in the luminescence properties, prompting the search for new HOFs for specific applications. 10–12,16,18–23 Also, HOFs can serve as a host for guest molecules (drugs, ions, chromophores) with specific capabilities. This multifunctionality expands the potential applications of HOFs in a wide variety of fields, not limited to photonics, such as sensing, catalysis, and drug delivery.…”
