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...

In the history of science there lie many Hidden Figures. Quite some are female or of color. Anna Tiefel from Regensburg honors their work by utilizing it to bring the topic of past and present inequalities to attention. Her lively talk organized by JCF inspires to shape a better future.

Cooperation is Key! @evaheviagroup.bsky.social highlighted in her GDCh Lecture on arene functionalization yesterday how cooperation is essential - not just between experimental and theoretical chemists, but mainly leveraging cooperation of diverse metal pairings. That's the power of teamwork!

Conveying the fascination of chemistry and natural sciences to graduating pupils – that's we successfully achieved today. We look forward to welcoming some of these pupils as new students at TU Chemnitz next semester.

It's always the days that pupils come to the lab, that you get to realize: The basic understanding of the world for a trained chemist seems to be MAGIC for the rest of the world.
In our case today it was only colors... not the actual world shaping science we do on a day to day basis in our lab.
