A series of 11 low melting ionic liquids based on meso-substituted A3B -porphyrins and A2B2-porphyrins containing one or two pyridyl substituents have been synthesized in high yields. Three of them are liquids at room temperature. All these porphyrinic salts were characterized by1H NMR,19F NMR, MALDI-TOF mass spectrometry, elemental analysis and UV-visible spectroscopy. The thermal properties and conductivity values of these salt derivatives have been also measured. A specific conductivity value of up to 4 mS.cm-1could be obtained for a compound having the counter-anion B(C6F5)4-.
