“…Metal–organic frameworks (MOFs) are porous crystalline hybrid materials with an outstanding relevance in material science. Owing to their advanced properties like high specific surface areas, tunable cavities/pore apertures, and large accessibility to many molecular guests, MOFs have been applied in several technological fields such as photonics, 1,2 chemical sensors, 3–5 optoelectronic devices, 6–8 gas storage, 9,10 catalysis, 11,12 drug delivery, 13–15 and, more recently, as solid-state flexible supercapacitors. 16,17…”
