A fluorinated metal–organic framework NOTT-108 with single pure-phase has been synthesized for the first time, which has enabled us to examine the effect of the substituted fluorine atoms on the methane storage. The activated NOTT-108a shows a permanent porosity comparable to its isoreticular NOTT-101a but exhibits a higher volumetric methane storage capacity of 247 cm³ (STP) cm^–3 and a working capacity of 186 cm³ (STP) cm^–3 (at 298 K and 65 bar) than 237 cm³ (STP) cm^–3 and 181 cm³ (STP) cm^–3 of NOTT-101a, attributed to the higher polarity/dipole moment of C–F bonds compared to that of C–H bonds for the enhanced electrostatic interaction with methane molecules.
