Engineering N-site isomerism in donor-acceptor covalent organic frameworks for efficient Fenton-like water purification
Covalent organic frameworks (COFs) have emerged as promising candidates for singlet oxygen (1O2) generation via peroxymonosulfate (PMS) activation, yet their structure-property-activity relationships remain poorly understood. Herein, three constitutionally isomeric donor-acceptor COFs (TF-22Bpy, TA-22Bpy and TA-33Bpy)...
