Methods of making formamidinium iodide and uses thereof

Abstract

The present disclosure relates to a method for making formamidinium iodide compound. The method comprises mixing a first precursor, which contains formamidinium ions, with a first liquid (step (a)); mixing a second precursor, which contains iodide ions, and a second liquid (step (b)); preparing a reaction mixture (step (c)) by mixing the resulting mixture in step (a) with the resulting mixture in step (b); introducing a third liquid (step (d)) to the reaction mixture in step (c); mixing the reaction mixture (step (e)); collecting the solution which contains formamidinium iodide product (step (f)); and isolating formamidinium iodide product by removing solvents in the product solution (step (g)).
