Abstract
To generate large single crystals of 3D covalent organic frameworks, the active use of ionic additives, which can greatly impact crystal size, is proposed. The crystal size ranking was found to be in accordance with the Hofmeister series and Gutmann donor number, providing a useful strategy to enhance crystal size and, consequently, generate COF-300 single crystals of >200 μm in size.
