Regioisomerism-Driven Microenvironment Modulation in Three-Dimensional Covalent Organic Frameworks for Selective H2O2 Photosynthesis.
Internal microenvironment within covalent organic frameworks (COFs) is essential for photocatalytic performance. Nevertheless, retaining the chemical composition of building blocks hinders precise control over internal charge distribution. Herein, a regioisomerism-driven strategy was adopted to engineer the framework m...
