Conjugated　microporous　polymers　(CMPs)　have　been　considered　a　type　of　promising　visible-light-driven,　organic　photocatalysts.　However,　apart　from　designing　high-performance　CMPs　from　a　molecular　perspective,　little　attention　is　paid　to　improving　the　photocatalytic　properties　of　these　polymers　through　macrostructural　regulation.　Herein,　we　prepared　a　kind　of　hollow　spherical　CMPs　involving　carbazole　monomers　and　studied　their　performance　on　the　selective　photocatalytic　oxidation　of　benzyl　alcohol　under　visible　light　irradiation.　The　results　demonstrate　that　the　introduction　of　a　hollow　spherical　structure　improves　the　physicochemical　properties　of　the　as-designed　CMPs,　including　the　specific　surface　areas,　optoelectronic　characteristics,　as　well　as　photocatalytic　performance,　etc.　In　particular,　the　hollow　CMPs　can　more　effectively　oxidize　benzyl　alcohol　compared　to　pristine　ones　under　blue　light　illumination,　and　produce　＞1　mmol　of　benzaldehyde　in　4.5　h　with　a　yield　of　up　to　9　mmol.g(-1).h(-1),　which　is　almost　5　times　higher　than　that　of　the　pristine　ones.　Furthermore,　such　hollow　architecture　has　a　similar　enhanced　effect　on　the　oxidation　of　some　other　aromatic　alcohols.　This　work　shows　that　the　deliberate　construction　of　specific　macrostructures　can　better　arouse　the　photocatalytic　activity　of　the　as-designed　CMPs,　which　will　contribute　to　the　further　use　of　these　organic　polymer　semiconductors　in　photocatalysis　areas.　(c)　2023　Elsevier　Inc.　All　rights　reserved.
