Polymeric　carbon　nitride　(CN)　has　evoked　considerable　attention　in　photocatalysis,　however,　its　p-　deficiency　conjugated　frameworks　engendering　weak　visible-light　absorption　and　rapid　charge　recombi-nation　hinder　the　practical　utilizations.　Herein,　a　novel　donor　&　ndash;acceptor　(D-A)　conjugated　polymer　based　on　triptycene　incorporated　carbon　nitride　(T-CN)　has　been　facilely　prepared　by　thermal　copolymerization　of　melamine　and　2,6,14-triaminotriptycene.　Combined　with　the　density　functional　theory　(DFT)　calcula-tions,　it　is　found　that　the　formation　of　intramolecular　charge　transfer　and　the　extended　p-conjugative　effect　in　the　D-A　structure　contribute　to　a　broadened　light-harvesting　spectral　range,　a　higher　charge　sep-aration/transfer　efficiency　and　more　active　sites　of　T-CN　for　photoredox　reactions.　The　T-CN　catalyst　accomplished　superior　visible-light　photocatalytic　performance　in　both　hydrogen　evolving　and　carbon　dioxide　reduction.　The　optimal　T-CN　catalyst　exhibited　the　highest　hydrogen　evolution　rate　of　80.9　+/-　1.　3　&　micro;mol　center　dot　h-1　and　carbon　monoxide　production　rate　of　8.1　+/-　0.2　&　micro;mol　center　dot　h-1,　which　are　ca.　8-fold　and　20　fold　of　bulk　CN,　respectively.　The　convenient　strategy　of　constructing　D-A　conjugated　structure　opens　up　a　new　intriguing　avenue　toward　the　rational　creation　of　efficient　polymeric　nanomaterials　for　versatile　applications　of　solar　fuel　production.　(c)　2022　Elsevier　Inc.　All　rights　reserved.　Superscript/Subscript　Available＜/comment
