Dominik‘s second PhD paper in Chem Mater reports on side chain-free ionenes as n-type OECTs with record-high performance. Check out this beautiful collaboration with the Fabiano Group. #Chemsky
Molar Mass Improves the Performance of n-Type Organic Electrochemical Transistors
We report on the synthesis and use of two side-chain-free ionenes with varying heteroatoms, PFu and PTh, for n-type accumulation-mode OECTs. Compared to PTh, PFu is more challenging to make, less stab...

What have #CO2, #microplastics and #PFAS in common? Once out in the atmosphere, they can’t be controlled. Polymer science provides solutions to all these areas. The latest work of our group reports hydroxide-conducting membranes that are fluorine-free and mechanically robust for use in #AEMWE.
Kinking Matters: meta-Terphenyl Improves Hydroxide Conductivity of Mechanically Robust Fluorine-Free Poly(arylene piperidinium) Copolymers for Anion Exchange Membranes
Poly(arylene piperidinium) (PAP) polymers have emerged as promising candidates for applications as anion exchange membranes (AEMs) and have seen some commercial use in the form of PiperION by Versogen...

🚨Excited to share my latest work🚨
While the two-point interaction plays a crucial role in stabilizing the folded conformation🤝 in solution, we observed an unexpected deepening of color🌡️in the immobilized state when one of the interactions was disrupted✂️

Chain folding of carbazole-donor containing polymers via a two-point interaction with naphthalene monoimide-based acceptors
Linear polymers carrying electron-rich dialkoxy-carbazole (DACBZ) units linked by flexible oligooxyethylene segments were induced into a zigzag folded state by an external folding agent, which carries...
