Photocatalyst　surface　restructuration　is　of　immense　practical　importance　for　solar　energy　utilization.　Herein,　we　present　an　ingenious　strategy　to　bridge　pi-conjugated　molecules　into　the　framework　of　a　polymeric　semiconductor.　This　endows　the　catalyst　with　increased　charge　transfer　and　separation　efficiency,　resulting　in　an　improved　photoactivity.　Moreover,　the　modified　photocatalysts　exhibit　high　structural　stability　and　photoactivity.　These　results　illustrate　a　novel　method　of　integrating　functional　units　to　construct　new　photocatalysts　for　sustainable　photocatalysis.
