Conjugated　polymers,　comprising　fully　π-conjugated　systems,　present　a　new　generation　of　heterogeneous　photocatalysts　for　solar-energy　utilization.　They　have　three　key　features,　namely　robustness,　nontoxicity,　and　visible-light　activity,　for　photocatalytic　processes,　thus　making　them　appealing　candidates　for　scale-up.　Presented　in　this　Minireview,　is　a　brief　summary　on　the　recent　development　of　various　promising　polymer　photocatalysts　for　hydrogen　evolution　from　aqueous　solutions,　including　linear　polymers,　planarized　polymers,　triazine/heptazine　polymers,　and　other　related　organic　conjugated　semiconductors,　with　a　particular　focus　on　the　rational　manipulation　in　the　composition,　architectures,　and　optical　and　electronic　properties　that　are　relevant　to　photophysical　and　photochemical　properties.　Some　future　trends　and　prospects　for　organic　conjugated　photocatalysts　in　artificial　photosynthesis,　by　water　splitting,　are　also　envisaged.　©　2016　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
