Stimuli-responsive smart materials, as an emerging material, can fulfill reversible transformation of chemical/physical properties under external stimuli such mechanical stress, light, and electricity, which has the highlights rapid response, designable structure, function. Two ionic hydrogen-bonded organic frameworks (iHOFs 36–37) were synthesized by self-assembly bis(benzene-o/p-sulfonic acid)-naphthalenediimide (o/p-H2BSNDI) two basic ligands. The naphthalenediimide (NDI) was introduced into material to equip iHOFs 36–37 with radical-driven photochromic behavior. proton conductivity iHOF-37 demonstrated a maximum 6.50 × 10–4 S·cm–1 at 98% RH 100 °C, it increased 9.10 10–3 due dual free radical synergism following UV irradiation (NDI viologen), represents significant 14-fold enhancement. Furthermore, incorporation chitosan (CS) matrix forms composite membranes. 5%-iHOF-37/CS membrane reached up 5.70 10–2 90 8.08 after irradiation. This work reveals radicals generated NDI viologen derivatives, whose synergistic action plays role in enhancing membranes, rendering rational design stimuli-responsive materials feasible.
