WebIn this work, a series of vinylene-bridged two-dimensional (2D) COFs are synthesized by Knoevenagel condensation of tricyanomesitylene with ditopic or tritopic aromatic … WebFeb 15, 2024 · Herein we proposed a facile end-capping strategy to synthesize a series of new vinylene-linked COFs with tunable band gap and hydrophilicity. As a result, the COFs exhibited much improved visible-light-driven H 2 evolution properties via optimizing the species, positions and contents of end-capping groups. In brief, an electron-deficient 2,4,6 …
