WebSep 16, 2024 · Crystallize the compound of interest. This step assumes that any colored impurities and insoluble impurities have been removed by appropriate steps above. Remove any excess solvent by boiling it off or blowing it off with a gentle stream of air, or by rotary evaporation. Start from a solution saturated with the solute at the boiling point. WebHighly fused, fully conjugated aromatic compounds are interesting candidates for organic electronics. With higher crystallinity their electronic properties improve. It is shown here that the crystallization of three archetypes of such molecules-pentacenetetrone, indigo, and perinone-can be achieved hydrothermally.
