Abstract

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 iso-reticular 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 cm}u3^ (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 enhanced electrostatic interaction with methane molecules.
