Ladder polymers of intrinsic microporosity from superacid-catalyzed Friedel-Crafts polymerization for membrane gas separ...
Polymers of intrinsic microporosity have attracted comprehensive attention in membrane-mediated gas separation because of their rigid and contorted structure that facilitates well-defined microporosity for fast and selective gas transport. We report a new macromolecular design synthesizes semi-ladder and fully-ladder polymers of intrinsic microporo...

Highly Selective Benzimidazole-Based Polyimide/Ionic Polyimide Membranes for Pure- and Mixed-Gas CO2/CH4 Separation
This paper reports two new series of benzimidazole functionalized polyimides and ionic polyimides for highly selective membranes with great potential for natural gas sweetening. It has been demonstrated that both the -NH groups in the benzimidazole moieties and the corresponding ionic groups after N-quaternization tighten the microporous structure ...

Charged Block Copolymers: From Fundamentals to Electromechanical Applications
CONSPECTUS: Charged block copolymers are promising materials for next-generation battery technologies and soft electronics. Although once it was only possible to prepare randomly organized structures, nowadays, well-ordered charged block copolymers can be prepared. In addition, theoretical and experimental analyses of the thermodynamic properties o...
Alicyclic segments upgrade hydrogen separation performance of intrinsically microporous polyimide membranes
Even with high permeability, insufficient selectivity of intrinsically microporous polyimides is a major obstacle for large-scale membrane-based separation applications. The present work proposes to increase hydrogen separation performance by incorporating deliberately chosen alicyclic segments into Troger's Base (TB)-based polyimide backbones via ...

...
Poly(ionic liquid)s are an innovative class of materials with promising properties in gas separation processes that can be used to boost the neat polymer performances. Nevertheless, some of their properties such as stability and mechanical strength have to be improved to render them suitable as materials for industrial applications. This work explo...
Efficient charge carrier injection and balance achieved by low electrochemical doping in solution-processed polymer ligh...
Charge carrier injection and transport in polymer light‐emitting diodes (PLEDs) is strongly limited by the energy level offset at organic/(in)organic interfaces and the mismatch in electron and hole mobilities. Herein, these limitations are overcome via electrochemical doping of a light‐emitting polymer. Less than 1 wt% of doping agent is enough to...
Some mechanistic insights into the action of facilitating agents on gas permeation through glassy polymeric membranes
Incorporation of facilitating agents is one of the promising strategies being researched in recent years to cross the Robeson bounds for gas separations using polymeric membranes. The ways in which such inclusions modify the performance of membranes are not always clear. Here, we study the performance of two glassy membranes, Polyfurfuryl alcohol a...
