Sep. 16, 2020: Our article "Advanced Heteroatom-doped Nanoporous Carbon Membranes Assisted by Poly(ionic liquid) Design and Engineering" is published in Accounts of Materials Research, http://dx.doi.org/10.1021/accountsmr.0c00010.
In this article, we highlight the latest discovery and proceedings of heteroatom-doped porous carbon membranes (HPCMMs), particularly the advancements in how to tailor structures and properties of HPCMMs by rational structure design of porous polymer membranes as sacrificial template built up especially from heteroatom-rich poly(ionic liquid)s (PILs). We will also stress the carbonization craft, and the state-of-the-art electrochemical applications for HPCMMs. Key factors and thoughts in heteroatom doping and porous systems in HPCMMs are discussed. A future perspective of the challenges and promising potential of HPCMMs is cast on the basis of these achievements.

July 2th, 2020: Our article "Polymer-derived Heteroatom-doped Porous Carbon Materials" is published in Chemical Reviews, 2020, DOI: 10.1021/acs.chemrev.0c00080.
This Review comprehensively surveys the progress in polymer-derived functional heteroatom-doped porous carbon materials (HPCMs) in terms of how to produce and control their porosities, heteroatom doping effects, and morphologies and their related use. We also provided our perspective on how to predefine the structures of HPCMs by using polymers to realize their potential applications in the current fields of energy generation/conversion and environmental remediation. We believe that these analyses and deductions are valuable for a systematic understanding of polymer-derived carbon materials and will serve as a source of inspiration for the design of future HPCMs.
June 25th, 2020: Our work entitled "Crosslinking of a Single Poly(ionic liquid) by Water into Porous Supramolecular Membranes" is published in Angew. Chem. Int. Ed., 2020, DOI: 10.1002/anie.202002679!
In this work, we discovered a general one-step approach to fabricate supramolecular porous polyelectrolyte membranes (SPPMs) from a single poly(ionic liquid). The experimental results and theoretical simulation suggested that SPPMs were formed by a hydrogen bond-induced phase separation of a PIL between its polar and apolar domains, which were linked together by water molecules. Such SPPMs could switch porosity upon thermal stimuli, as exemplified by dynamically adaptive transparency to thermal fluctuation.

May 14th, 2020: Our Joint work with Prof. Jiayin Yuan at Stockholms University on Hydrazine-enabled One-step Synthesis of Metal Nanoparticle-Functionalized Gradient Porous Poly(ionic liquid) Membranes is published on Macromol. Rapid Commun., 2020, 202000143.!
In this communication, we demonstrated a one-step strategy toward MNP-functionalized gradient porous poly(ionic liquid) membranes via using hydrazine as a reductive activation reagent. The distinctive feature of this membrane fabrication method is that the porous membrane formation and the metal nanoparticals production were completely in the same step in one material, thus it readily enables incorporation of desirable MNPs into PPMs. This discovery provides fascinating opportunities to prepare multifunctional membranes for expanded applications.
