【摘要】 近来，以共轭聚合物为沟道材料的有机电化学晶体管(OECT)因其易于制备、具有离子–电子转换能力和生物界面相容性而成为研究热点。然而，已报道的用于OECT沟道材料的大多是p型共轭聚合物，而基于n型共轭聚合物开发的OECT则很少，而不平衡的发展阻碍了复杂互补电路的实现。最近被报道的新兴n型共轭聚合物半导体Poly (benzimidazobenzophenanthroline)(BBL) OECT为解决上述问题提供了一个有效的方案。但BBL薄膜本身具有脆性无法拉伸，无法满足柔性器件的使用需求，大大阻碍了其应用及发展。本工作中，我们提出了一种器件可拉伸的n型BBL OECT器件的制备方法，并验证了其在汗液传感方面的可行性。更多还原

【Abstract】 Recently, organic electrochemical crystals(OECT) using conjugated polymers as channel materials have become a hot research topic due to their ease of preparation, ionelectron conversion capability and biointerface compatibility. However, most of the reported OECT channel materials for OECT are p-type conjugated polymers(hole transport), while few OECTs have been developed based on n-type conjugated polymers(electron transport),and the unbalanced development hinders the realization of complex complementary circuits.The recently reported n-type Poly(benzimidazobenzophenanthroline)(BBL) OECT of polyconjugated polymers provides an effective solution to the above problem. However, BBL films are inherently brittle and cannot be stretched to meet the use of flexible devices, which greatly hinders their application and development. In this work, we propose the preparation of a device stretchable n-type BBL OECT device and verify its feasibility for sweat sensing.更多还原
