Planarity-Engineered 1,2,3-Triazole-Based 1D Covalent Organic Frameworks for Enhanced Visible-Light Photocatalytic C-3 Thiocyanation of Indoles

Covalent organic frameworks (COFs) have emerged as efficient metal-free photocatalysts for green chemical synthesis and environmental remediation. However, their performance is often limited by interlayer π-π stacking, which hampers charge...
