Achieving Zero‐Temperature Coefficient Point Behavior by Defect Passivation for Temperature‐Immune Organic Field‐Effect Transistors

Jiannan Qi, Kai Tie, Yue Ma, Yinan Huang, more

Advanced Materials > 36 > 25 > n/a - n/a

Organic field‐effect transistors (OFETs) have broad prospects in biomedical, sensor, and aerospace applications. However, obtaining temperature‐immune OFETs is difficult because the electrical properties of organic semiconductors (OSCs) are temperature‐sensitive. The zero‐temperature coefficient (ZTC) point behavior can be used to achieve a temperature‐immune output current; however, it is difficult...

Dong Zhang, Shuyu Li, Shaosong Gao, Siyao Fu, more

Chinese Journal of Chemistry > 42 > 14 > 1563 - 1570

The organic cocrystal strategy has provided a convenient and efficient platform for preparing organic photothermal materials. However, the rapidly directional preparation of cocrystals with desirable photothermal properties remains challenging due to a lack of suitable design ideas. Here, two new photothermal cocrystals, MTC and MFC, based on acceptor molecules (TCNQ and F₄TCNQ) with different electron‐withdrawing...

Overcoming the Unfavorable Effects of “Boltzmann Tyranny:” Ultra‐Low Subthreshold Swing in Organic Phototransistors via One‐Transistor‐One‐Memristor Architecture

Shuyuan Yang, Jiangyan Yuan, Zhaofeng Wang, Xianshuo Wu, more

Advanced Materials > 36 > 23 > n/a - n/a

Organic phototransistors (OPTs), as photosensitive organic field‐effect transistors (OFETs), have gained significant attention due to their pivotal roles in imaging, optical communication, and night vision. However, their performance is fundamentally limited by the Boltzmann distribution of charge carriers, which constrains the average subthreshold swing (SS_ave) to a minimum of 60 mV/decade at room...

Angewandte Chemie > 136 > 23 > n/a - n/a

Two‐electron oxygen reduction reaction (2e⁻ ORR) is a promising method for the synthesis of hydrogen peroxide (H₂O₂). However, high energy barriers for the generation of key *OOH intermediates hinder the process of 2e⁻ ORR. Herein, we prepared a copper‐supported indium selenide catalyst (Cu/In₂Se₃) to enhance the selectivity and yield of 2e⁻ ORR by employing an electronic metal–support interactions...

Yuexin Gao, Yunzhe Ke, Tianzuo Wang, Yibo Shi, more

Angewandte Chemie International Edition > 63 > 20 > n/a - n/a

Conjugated polymers (CPs) with low crystallinity are promising candidates for application in organic thermoelectrics (OTEs), particularly in flexible devices, because the disordered structures of these CPs can effectively accommodate dopants and ensure robust resistance to bending. However, n‐doped CPs usually exhibit poor thermoelectric performance, which hinders the development of high‐performance...

High ambipolar mobility emissive conjugated polymers (HAME‐CPs) are perfect candidates for organic optoelectronic devices, such as polymer light emitting transistors. However, due to intrinsic trade‐off relationship between high ambipolar mobility and strong solid‐state luminescence, the development of HAME‐CPs suffers from high structural and synthetic complexity. Herein, a universal design principle...
