Abstract

Abstract The integration of functional moieties through robust covalent linkages is crucial for enhancing the stability, structural diversity, and photocatalytic utility of covalent organic frameworks (COFs). Herein, we report the synthesis of a series of vinylene‐linked quinoline‐based COFs (MQ‐PT, MQ‐PB, and MQ‐BT) via Knoevenagel condensation of a newly designed C 3 ‐symmetric quinoline monomer. The methyl groups adjacent to the quinoline nitrogen atoms serve as reactive sites for coupling with aldehydes under mild, acid‐catalyzed conditions. The resulting vinylene‐linked quinoline‐based COFs exhibit high crystallinity, tunable light‐harvesting properties, and excellent physicochemical stability. Notably,…
