Efficient elimination of organics or oils in water has become a global concern due to their severely environmental pollution. In this work, two kinds of absorbents based on the doping of conjugated microporous polymers onto sponges (CMPs@sponges) were prepared by in situ Sonogashira‐Hagihara coupling reaction of the monomers in the presence of melamine sponge. The as‐synthesized CMPs@sponges possess excellent thermal and physicochemical stability. Owing to the excellent hydrophobic character of the CMPs@sponges, which exhibit high oil/water separation efficiency through adsorption process. The CMPs@sponges show desirable ability for the adsorption of oils and organic solvents with the values of 24–64 g/g and 13–36 g/g, and the adsorption properties remain unchanged after 10 cycles with excellent cycling stability. Even the CMPs@sponges are immersed in different pH solutions, which still maintain their original superhydrophobicity. In addition, CMPs@sponges can constantly separate and recover oil and organic solvent based on the help of vacuum pump, and the separation efficiency still remained above 95% after 10 repetitions. It was worth noting that the CMPs@sponges can remove not only the organic solvents but also the trace benzene contaminants from water, and with the removal rate of more than 85%. Furthermore, the as‐synthesized CMPs@sponges possess high oil/water separation properties that may be attributed to the physical adsorption, and the π‐π interactions and hydrophobic interactions. Therefore, due to the designable flexibility of CMPs, which make the CMPs‐based novel materials are excepted to an excellent candidate for applications of oil/water separation and water purification.

This Review provides a perspective on porous organic polymer‐photocatalyst composites obtained by coupling semiconductors and hydrophilic/hydrophobic polymers which do not modify the properties of the embedded photocatalysts, but can influence the efficiency of the overall catalytic process. Particular attention has been given to polymer composites in the form of monolithic hydrogel/sponge/aerogels obtained by dissolving the polymer in a solvent, which contains the photocatalyst dispersed, inducing gelation or solidification of the solution and subsequently removing the solvent by a drying process. The photocatalytic applications discussed here cover H2 evolution from water splitting, CO2 reduction, and organic synthesis. Indeed, the main aim of this Review is to outline an alternative perspective to the highly studied environmental photocatalytic applications, highlighting the photoactive properties of these composites thanks to the incorporation of semiconductors in the 3D porous structure of organic polymers. Finally the challenges and potential advances associated with the use of porous organic polymer‐photocatalyst composites for future scientific research are outlined.

“…Melamine sponge (MS) is a 3D porous material with high porosity, easy modification, low cost, environmental friendliness, good flexibility 25 and many other excellent characteristics, which has attracted considerable attention. In view of these outstanding peculiarities, it is often coated with functional polymers 26–28 to form composite materials with easy separation and high mechanical strength, which has been applied in dye removal, 29 oil–water separation, 30 catalysis 31 and other fields.…”
