A series of 11 low melting ionic liquids based on meso-substituted A(3)B-porphyrins and A(2)B(2)-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 by H-1 NMR, F-19 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(-1) could be obtained for a compound having the counter-anion B(C6F5)(4)(-)
