Here, we report the enhancement of ultraviolet (UV) detection capabilities through luminescent hydrogen-bonded organic frameworks (HOFs), with a particular focus on the amelioration brought by hydrogen isotope effects. An in situ deuterated HOF (DHOF) is proposed, which demonstrates exceptional UV detection sensitivity through luminescence quenching with a significantly lower limit of detection (LOD) of 1.02 × 10-7 J than that of the hydrogenated HOF (HHOF), showcasing superior UV detection performance compared to current discoloration methods and other HOF implementations.
