Abstract

Developing hydrogen-bonded organic frameworks (HOFs) with unique architectures and functions is of great significance but remains major challenges. Here, we have successfully created porphyrin-based HOF nanoflowers (HOF-199-f) using a well-designed liquid-phase ultrasonic method. These nanoflowers exhibit exceptional resistance-based near-room-temperature sensing properties, with a linear response (27.0–55.0℃), high resolution (0.54 % K⁻¹), high sensitivity (ΔR/R_T = 120.0 % at 34.5℃), fast response and recovery (97 s/41 s). This greatly outperform HOF-199, highlighting the importance of the nanoflower architecture of HOF-199-f. This work provides insights for designing advanced sensors using functional HOFs.
