Solvent-induced conformational changes in color-tunable hydrogen-bonded organic frameworks

Abstract

This study reports a pair of conformationally-induced, color-tunable hydrogen-bonded organic frameworks (HOFs) that share identical building blocks but exhibit distinct emission colors‒green and orange. A shift of up to 60 nm in their emission wavelengths is observed, which can be attributed to variations in conjugation and energy gap. These results provide in-depth insights into the structural regulation of emission in HOFs.
