Abstract:
A photochromic ionic hydrogen-bonded organic framework (iHOF-51) was synthesized by reacting organic carboxylic acids with amidinium salts. Fast, reversible, and high-contrast stimulus-responsive behavior via anionic radical naphthalenediimide (NDI) is observed. iHOF-51exhibits time-dependent photochromism in the powder state and excellent photoluminescent properties based on the synergistic interaction of FRET and radical anions in the 1%-iHOF-51-PVA composite membrane.
