Kinetic‐Directed Thermodynamic Repair Enables the Synthesis of High‐Strain 2D Sub‐Stoichiometric COFs

open access: yesAdvanced Science, EarlyView.
2D covalent organic frameworks are promising photocatalysts. Yet, precise synthesis of sub‐stoichiometric COFs remains challenging due to poor kinetic control. We propose a general strategy: tuning polymerization degree of kinetic intermediates via time or solvent polarity directs their thermodynamic repair into highly crystallization. Using [4+3]‐type
