More Information
Summary:The invention discloses free porphyrins, and a preparation method and application thereof. A method of modifying simple porphyrin is employed to synthesize three free porphyrins (3a, 3b, 3c), where 3b and 3c are new porphyrins; means of elemental analysis, infrared spectrum, UV-vis spectra and 1H NMR are adopted to characterize the prepared porphyrin compounds containing tailed imidazole. According to a test on catalytic performance of free porphyrins (3a-3b) on a Li / SOCl2 battery, the results show that compared with a bare battery, the above porphyrin compounds prolong discharge time of the Li / SOCl2 battery to different degrees, when the battery discharges to 2V, under conditions of room temperature of 25 DEG and resistance of 40 ohm; and capacity of the battery is increased substantially. Therefore, free porphyrins can affect electron transfer in the electronic Li / SOCl2 battery, so as to affect performance of the battery.
