Porous　liquids　are　a　newly　developed　porous　material　that　combine　unique　fluidity　with　permanent　porosity,　which　exhibit　promising　functionalities　for　a　variety　of　applications.　However,　the　apparent　incompatibility　between　fluidity　and　permanent　porosity　makes　the　stabilization　of　porous　nanoparticle　with　still　empty　pores　in　the　dense　liquid　phase　a　significant　challenging.　Herein,　by　exploiting　the　electrostatic　interaction　between　carbon　networks　and　polymerized　ionic　liquids,　we　demonstrate　that　carbon-based　porous　nanoarchitectures　can　be　well　stabilized　in　liquids　to　afford　permanent　porosity,　and　thus　opens　up　a　new　approach　to　prepare　porous　carbon　liquids.　Furthermore,　we　hope　this　facile　synthesis　strategy　can　be　widely　applicated　to　fabricate　other　types　of　porous　liquids,　such　as　those　(e.g.,　carbon　nitride,　boron　nitride,　metal–organic　frameworks,　covalent　organic　frameworks　etc.)　also　having　the　electrostatic　interaction　with　polymerized　ionic　liquids,　evidently　advancing　the　development　and　understanding　of　porous　liquids.　©　2017　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
