Chemical Science 035 3(c) ). In summary, the synthesis of four A 1 –A 2 -type conjugated polymers has demonstrated a remarkable improvement in efficiency ranging from 454% to 2461% when compared to their conventional D–A-type conjugated polymer counterparts. Advanced morphological analyses have unveiled the superior capability of A 1 –A 2 -type conjugated polymers in establishing compact network structures during photocatalytic hydrogen evolution reactions. These findings underscore the potential of A 1 –A 2 -type conjugated polymers as highly effective and promising materials for enhancing the efficiency of hydrogen evolution processes.
