Abstract
Abstract 2D covalent organic frameworks (2D‐COFs) have attracted extensive interest in solar energy to hydrogen conversion. However, insufficient light harvesting and difficult exciton dissociation severely limit the improvement of photocatalytic activity for COFs, thereby impeding the progression of this advanced field. In this work, two benzobisoxazole‐bridged and fully conjugated 2D‐COFs with triazine (COF‐JLU44) and pyrene (COF‐JLU45) units were constructed for the first time via Knoevenagel polycondensation, and they hold long‐range ordered structures, largely acceptable surface area, and fascinating photoelectric properties. Significantly, COF‐JLU45 exhibits an impressive hydrogen evolution rate of 272.5…
