Hydrogels are an attractive category of biointerfacing materials with adjustable mechanical properties, diverse biochemical functions, and good ionic conductivity. Despite these advantages, their application in electronics has been restricted because lack semiconducting they have traditionally only served as insulators or conductors. We developed single- multiple-network hydrogels based on a water-soluble n-type polymer, endowing conventional capabilities. These show electron mobilities high...
We designed and synthesized a series of fused-ring electron acceptors (FREAs) based on naphthalene-fused octacyclic cores end-capped by 3-(1,1-dicyanomethylene)-5,6-difluoro-1- indanone (NOICs) using bottom-up approach. The NOIC shares the same end groups side chains, as well similar cores. butterfly effects, arising from different methoxy positions in starting materials, impact design final FREAs, their molecular packing, optical electronic properties, charge transport, film morphology,...
Organic electrochemical transistors (OECTs) have attracted increasing attention due to their merits of high transconductance, low operating voltage, and good biocompatibility, ideal for biosensors. However, further advances in practical applications face challenges n-type performance poor stability. Here, it is demonstrated that wet-spinning the commercially available conjugated polymer poly(benzimidazobenzophenanthroline) (BBL) into highly aligned crystalline fibers enhances both OECT...
Conjugated polymers have demonstrated promising optoelectronic properties, but their brittleness and poor mechanical characteristics hindered fabrication into durable fibers textiles. Here, we report a universal approach to continuously producing highly strong, ultratough conjugated polymer using flow-enhanced crystallization (FLEX) method. These exhibit one order of magnitude higher tensile strength (>200 megapascals) toughness (>80 megajoules per cubic meter) than traditional...
Abstract To date, high‐performance organic electrochemical transistors (OECTs) are almost all based on conjugated polymers. Small molecules can be synthesized with high purity without batch‐to‐batch variations. However, small require highly crystalline films and good molecular packings to achieve charge carrier mobilities. Such features make their unsuitable for ion diffusion or packing distorted due diffusion, resulting in poor ion/charge transport properties slow response speed. Herein, it...
On-site or in-sensor biosignal transduction and amplification can offer several benefits such as improved signal quality, reduced redundant data transmission, enhanced system integration. Ambipolar organic electrochemical transistors (OECTs) are promising for this purpose due to their high transconductance, low operating voltage, biocompatibility, suitability miniaturized amplifier design. However, limitations in material performance stability have hindered application amplification. Here,...
Abstract Ambipolar organic electrochemical transistors (OECTs) can simplify manufacturing processes and reduce device footprints, yet their performance still lags behind p‐type n‐type counterparts due to limited molecular design strategies. Here, incorporating strong proquinoidal building blocks effectively addresses this challenge is demonstrated. Using a computational acceptor screening approach, three TBDOPV‐based polymers are designed synthesized: P(bgTBDOPV‐T), P(bgTBDOPV‐EDOT),...

To date, almost all the conjugated hydrophobic backbones, which impedes efficient ion diffusion/transport aqueous media. Here, we design synthesize a novel hydrophilic polymer building block, 4a‐azonia‐naphthalene (AN), drawing inspiration from biological systems. Because of strong electron‐withdrawing...
