High-performance n-type organic electrochemical transistors (OECTs) are essential for logic circuits and sensors. However, the performances of OECTs lag far behind that p-type ones. Conventional wisdom posits LUMO energy level dictates performance. Herein, we show engineering doped state is more critical OECT polymers. By balancing charges to donor moiety, could effectively switch a polymer high-performance material. Based on this concept, polymer, P(gTDPP2FT), exhibits record high...
Considerable efforts have been devoted to achieving stable acene derivatives for electronic applications; however, the instability is still a major issue such derivatives. To achieve higher stability with minimum structural change, CC units in acenes were replaced isoelectronic BN produce novel BN-embedded tetrabenzopentacene (BNTBP). BNTBP, planar structure, highly air, moisture, light, and heat. Compared its carbon analogue (TBP), embedment lowered highest occupied molecular orbital (HOMO)...
The donor, side chain, polymerization method, and processing solvent were systematically explored for diketopyrrolopyrrole (DPP) based donor–acceptor polymers to achieve high-performance fast-response organic electrochemical transistors.
Organic electrochemical transistors (OECTs) have shown great potential in bioelectronics and neuromorphic computing. However, the low performance of n-type OECTs impedes construction complementary-type circuits for low-power-consumption logic high-performance sensing. Compared with their p-type counterparts, electron mobility OECT materials is primary challenge, leading to μC* slow response speed. Nevertheless, no successful method has been reported address issue. Here, we find that charge...
Abstract Conjugated polymers that can efficiently transport both ionic and electronic charges have broad applications in next‐generation optoelectronic, bioelectronic, energy storage devices. 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...
Vacuum insulation panels (VIPs) are regarded as highly promising materials for thermal protection. Incorporating phase change extinction fibers into VIPs may become an effective approach to enhance both light shielding ability well transient capacity, however, the related research remains scarce. This study presents a design featuring gradient doping of within base material Al2O3 aerogel VIPs. The performance and optimal ratio this thoroughly investigated. Additionally, advantages brought by...

To date, high-performance organic electrochemical transistors (OECTs) are all based on polythiophene systems. Donor-acceptor (D-A) conjugated polymers expected to be promising materials for OECTs owing their high mobility and comparatively low crystallinity (good ion diffusion). However, the OECT performance of D-A lags far behind that polythiophenes. Here we synergistically engineered backbone, side chain a series diketopyrrolopyrrole (DPP)-based found redox potential, molecular weight,...
