Abstract

Light-Emitting Electrochemical Transistors

The cover image illustrates the integration of polyelectrolytes in light-emitting electrochemical transistors (LECTs), showcasing their multifunctional capabilities in electrochemistry and optoelectronics. In article number 2302207, Bright Walker, Han-Ki Kim, Jung Hwa Seo, and co-workers present LECTs that feature a streamlined device architecture enabled by electrochemical doping using poly(9-vinylcarbazole) doped with lithium ions (Li⁺) and copper (II) ions (Cu²⁺). The synergistic effects of these hybrid polyelectrolytes markedly enhance electron-hole recombination efficiency, resulting in bright and efficient electroluminescence.

掺杂聚（9-乙烯基咔唑）基聚电解质的混合氧化物/聚合物晶体管中的双极电荷注入和亮光发射（Adv. Mater. Technol.）

发光电化学晶体管封面图片展示了发光电化学晶体管（LECTs）中聚电解质的集成，展示了其在电化学和光电子学方面的多功能性。在文章编号 2302207 中，Bright Walker、Han-Ki Kim、Jung Hwa Seo 及其合作者介绍了发光电化学晶体管，该晶体管采用掺杂锂离子（Li+）和铜（II）离子（Cu2+）的聚（9-乙烯基咔唑）电化学掺杂，从而实现了精简的器件结构。这些混合聚电解质的协同效应显著提高了电子-空穴重组效率，从而产生明亮高效的电致发光。
