Natalie attended the MRS Spring Meeting 2026 in Honolulu and gave two invited talks about organics photocatalysis and highly doped polymers!

Last Friday, Gopika presented the first results of her PhD at the Swiss Photochemistry Symposium in Fribourg. Very well done Gopika! Anouk and Maxi joined as participants, and we had enriching discussions with the other members of the field based in Switzerland. Thanks a lot to the organizers for this…

Tom van der Pol et al., report a new operation regime in BBL, a polymer deswelling driven by water expulsion owed to polymer-cation interactions upon n-type electrochemical doping. Congrats to the team, we are proud to have contributed with terahertz spectroscopy. Now in Nature Materials!

Why do some polymers tolerate high doping levels and keep increasing their conductivity, while others decay at similar doping levels? Our PhD student, Basil, explores this in his first paper as first author, now published in Advanced Materials.

Our PhD student Kaishuai Zhang attended the e-MRS spring 2026 conference where he delivered a talk on the dynamics of electrochromic switching in covalent organic frameworks.

Julien presented at SPIE photonics! He showed his first hyperspectral images of OECTs. The doping and dedoping can be monitored in the channel and on the transparent ITO electrodes at the same time. Time resolved images have also been acquired, giving a unique insight into the doping mechanisms governing the…

New PhD in the house! Last Wednesday, Isabelle successfully defended her PhD thesis on the spectroscopic investigation of doping in organic mixed ionic–electronic conductors. You did a fantastic job, and we are super proud of you! All the best for the future ahead of you, you will be missed here!

A warm welcome to Varun Subudhi who is joining as a Ph.D. student within the MSCA doctoral network FADOS. Varun completed his Integrated M.Sc. degree in Physics at NISER, Bhubaneswar, India, where he specialized in nanoelectronics and organic device physics. At FemtoMat, he will focus on charge transport in doped…

We are thrilled to announce our new publication by Priscila! She studied why P3HT outperforms more polar analogues in OECTs. Thanks to the groups of Sahika Inal and Christian Nielsen for the great collaboration on this project!

New PhD in the house! Last Friday, Cedric successfully defended his PhD thesis on excitation-energy and field-driven ultrafast charge processes in organic semiconductors! You did a great job, and we wish you all the best for the future!
