DOI: 10.1002/adom.202501751
Abstract: The covalent linkages in covalent organic frameworks (COFs) extend π‐electron delocalization, providing an ideal platform for constructing materials with excellent third‐order nonlinear optical (NLO) properties. However, excessive π‐conjugation within COF planes leads to increased exciton… read more here.
