Abstract
- Two new solid hybrid molecular materials [PyPS]HPWVO and [PyPS]HPWVO have been synthesized from 1-(3-sulfonic group) propyl-pyridine ionic liquid cation and tungstovanadophosphoric anion with the Dawson structure. They were characterized by element analysis, impedance spectroscopy (IS), IR- and UV-spectroscopy. The formation of the hybrid molecular compounds with the Dawson structure was showed. Ion conductivity of [PyPS]HPWVO and [PyPS]HPWVO are 3.99 × 10 and 7.37 × 10 S cm at 18°C and 55% relative humidity respectively. The activation energies of proton conductivity are 28.2 and 26.7 kJ mol respectively. [ABSTRACT FROM AUTHOR]
