You live in Strasbourg? You enjoy social time and science? Join me, CNRS Alsace researcher at ICPEES, at Nerd Nite tonight (Friday 23rd)! It is fully free at the Shadok bar: 25 presqu'ile André Malraux, Rue du Bass. d'Austerlitz, 67100 Strasbourg.

🌱 5-month Internship in 2026 at CNRS Strasbourg (France)! 🌱
You care about the environment and know OECTs? Join my group to develop organic sensors to detect *glyphosate* in freshwater.
For details, contact olivier.bardagot@cnrs.fr and patrick.leveque@unistra.fr.

#MATSUS in Valencia, Spain. What a nice conference focused on the development of next-gen OECTs and understanding of the fundamental mechanisms.
Thank you to @scottkeene.bsky.social, @SabineLudwig, @TomVanDerPol for the organisation and kind invitation 🧠☀️

Interesting paper about the benefit of blending 2 n-type polymers (here N2200 and glycolated-NDI derivates) to enhance the performance of OECTs. By @cgbischak.bsky.social and his team. onlinelibrary.wiley.com/doi/abs/10.1...

Figure 5 finally presents how aligned OECTs enhance the stability over 1000 pulsing cycles compared to non-aligned ones. Note that the stability remains the key parameter to enhance. Limiting the (de)doping range enhances stability, reaching 93% of Ids retention, at the expense of Ids amplification.

Figure 4 summarizes the enhancement of the normalized-gm (recalculated from the literature) and µC* values over the years for aqueous-based OECTs, underlining the unprecedented values achieved with aligned PBTTT-8O. A naive sketch tentatively illustrates the key parameters benefiting aligned films.

Figure 3 presents you how correlating the evolution of the absorbance of the channel vs. the Ids current flowing through over 1000 ON/OFF cycles informs us on the mechanisms of degradation. The aligned channels demonstrated faster response and higher cycling stability compared to non-aligned ones.

Figure 2 highlights that the > x10 Ids output enhancement is directly found on the transfer curves (raw data, independent of any model)

Figure 1 shows that aligning the polymer chain along the OECT channel direction does not imapct the electrochemical doping behaviour comapred to non-aligned channel

➡️ Paper out in Adv. Mater. ⬅️ Want to boost the IDS output of an OECT? By aligning the chains of a high-perf' single-ether PBTTT, we reached an unprecedented signal amplification (gmL/Wd = 2 580 S cm-1). Collab:

Versatile Direct (Hetero)Arylation Polymerization of Electro‐Deficient Unsubstituted Thiazolo[5,4‐d]Thiazole: A Tool to Lower the LUMO Level An unsubstituted thiazolo[5,4-d]thiazole (TzTz) unit is used to synthesize a series of novel semiconducting polymers via eco-friendly direct arylation polymerization. These TzTz-based copolymers, wit....

A new paper is out! By combining unsubstituted thiazolo[5,4-d]thiazole (TzTz) and direct (hetero)arylation polymerisation (DHAP), ambipolar and n-type conjugated polymers with improved backbone planarity and deep LUMO levels have been synthesised.
