A synthetic and modification method to obtain water‐compatible, visible‐light‐active, conjugated, microporous polyazulene networks as pure organic, highly stable, reusable, and heterogeneous photocatalysts in aqueous medium by a simple protonation method was investigated. The water compatibility and photocatalytic activity of the hydrophilic polyazulenes were demonstrated in the photoreduction reaction of Cr VI to Cr III for heavy‐metal‐contaminated waste‐water treatment. Furthermore, a light‐induced cascade reaction mechanism with the use of additional abundant metal cations such as Fe III or Cu II as co‐catalysts was also described. This design strategy could offer a clean and cost‐effective solution to obtain water‐compatible, pure organic, photoactive polymers with a broader potential for other applications in aqueous media under sustainable and environmentally friendly conditions.
