Proton and fluorine diffusivity and ionic conductivity of 2-fluoropyridinium triflate (2-FPTf) and proton and fluorine diffusivity, ionic conductivity, and viscosity of trifluoromethanesulfonic acid (TFMSA) monohydrate have been measured over a wide range of temperatures. Diffusivities were measured using the pulsed-gradient spin-echo (PGSE) technique on a 300 MHz NMR spectrometer. Conductivities were measured using electrochemical impedance spectroscopy (EIS) on standard equipment and viscosities were determined using a Cannon-Ubbelohde viscometer. For 2-FPTF, the diffusivity of mobile protons increased from 1.84+/-0.06 x 10(-11) m2/s at 55 degC to 1.64+/-0.05 x 10(-10) m2/s at 115 degC while the diffusivity of 2-fluoropyridine fluorines increased from …
