Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has been recently proposed for Raman sensing of redox-active species in solution. Here, we investigated the rationale this approach through systematic experiments, which spectrum PEDOT:PSS was analyzed presence either nonoxidizing or oxidizing electrolytes. The results demonstrated that spectra precisely reflect conformation PEDOT units and their interactions with PSS. Two different responses were observed. In case electrolytes, effect charge transfer is accurately transduced changes. On other hand, reduction induces a progressive separation between PSS chains, decreases mutual interaction. This stimulus determines characteristic variations intensity, shape, position spectra. However, same effects can be obtained by increasing concentration electrolytes deprotonating chains. poses severe limitations to use type sensing. study allows us revise most reported literature clear model, setting new basis investigating dynamics mixed electronic/ionic conductive polymers.

Organic mixed ionic-electronic conductors, such as poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), are essential materials for the fabrication of bioelectronic devices due to their unique ability couple and transport ionic electronic charges. The growing interest in has led development organic electrochemical transistors (OECTs) that can operate aqueous solutions transduce signals biological origin into measurable signals. A common challenge with OECTs is maintaining stability performance PEDOT:PSS films operating under conditions. Although conventional approach blending dispersions a cross-linker (3-glycidyloxypropyl)trimethoxysilane (GOPS) helps ensure strong adhesion device substrates, it also impacts morphology thus electrical properties films, which leads significant reduction OECTs. In this study, we instead functionalize only surface substrates GOPS introduce silane monolayer before spin-coating dispersion on substrate. all cases, having blend increased metrics, three times higher conductivity, volumetric capacitance, mobility-capacitance product [μC*] value OECT devices, ultimately leading record 406 ± 39 F cm-1 V-1 s-1 amorphous PEDOT:PSS.
