Band structure tunable synthesis of photocatalytic porous aromatic frameworks via Scholl reaction
Porous aromatic framework (PAF) materials with π-π conjugation system based on Scholl reaction were found to exhibit satisfying photocatalytic performance, that can successfully degrade Rhodamine B (RhB) and colorless phenol. By selecting different multiple-phenyl building blocks, six kinds of PAF m...
