Abstract A rapidly growing interest in organic bioelectronic applications has spurred the development of a wide variety mixed ionic‐electronic conductors. While these new conductors have enabled community to interface electronics with biological systems and efficiently transduce signals (ions) into electronic signals, current materials selection does not offer sufficient selectivity towards specific ions relevance without use auxiliary components such as ion‐selective membranes. Here, we present molecular design an n‐type (electron‐transporting) perylene diimide semiconductor material decorated pendant oligoether groups facilitate interactions cations Na + K . Using cyclic 15‐crown‐5 motif, find that resulting conductor PDI‐crown displays strong dependence on size electrolyte cation when tested electrochemical transistor configuration. In stark contrast low response order 1 μA observed aqueous sodium chloride, nearly 200‐fold increase is potassium chloride. We ascribe high extended aggregation therefore efficient charge transport presence due favourable sandwich‐like structure between two adjacent motifs ion.

Organic mixed ionic-electronic conductors (OMIECs) have emerged as promising materials for biological sensing, owing to their electrochemical activity, stability in an aqueous environment, and biocompatibility. Yet, OMIEC-based sensors rely predominantly on the use of composite matrices enable stimuli-responsive functionality, which can exhibit issues with intercomponent interfacing. In this study, approach is presented non-enzymatic glucose detection by harnessing a newly synthesized functionalized monomer, EDOT-PBA. This monomer integrates electrically conducting receptor moieties within single organic component, obviating need complex preparation. By engineering conditions electrodeposition, two distinct polymer film architectures are developed: pristine PEDOT-PBA molecularly imprinted PEDOT-PBA. Both demonstrated proficient binding signal transduction capabilities. Notably, (MIP) architecture faster stabilization upon uptake while it also enabled lower limit detection, standard deviation, broader linear range sensor output compared its non-imprinted counterpart. material design not only provides robust efficient platform but offers blueprint developing selective diverse array target molecules, tuning units correspondingly.

Abstract Organic electrochemical transistors (OECTs) possess low operating voltage and excellent amplification capability show promising applications in biosensors flexible electronics. However, the active layers of OECTs are usually dense films, which limited ion penetration/transport, resulting performances OECTs. Here, unprecedented high‐performance multifunctional based on nanoporous (mainly 2–60 nm), high‐specific‐surface‐area (255–281 m 2 g −1 ), conjugated polymer aerogel films developed. The structures effectively facilitate leading to significantly enhanced transconductance (48.5–53.5 mS) on/off ratio (6.4 × 10 4 ) compared with those devices. OECT‐based glucose sensors exhibit an ultralow detection limit 1 p , approximately two three orders magnitude lower than previously reported OECT sensors, ultrabroad range –5 . They can detect trace amounts sweat, serum, saliva, urine real time. Moreover, be used for artificial synapses electrocardiogram monitoring. This work provides a powerful strategy toward highly sensitive biosensors, synapses, electrophysiological signal
