对柔性电子产品的需求不断增长，要求开发可集成到新兴显示和标签技术中的低电压和高迁移率有机薄膜晶体管（OTFT）。具有综合和平衡的介电性能的聚合物浆料（即，它们的绝缘特性和与有机半导体的相容性之间的良好平衡）被认为对于这一目的特别重要。在这里，我们介绍了一种简单但高效的策略，以实现这一目标，通过使用一种新型的共聚物作为载体。得益于保证介电性能的高链堆积密度和优化有机半导体分子堆积的表面极性，这种合理设计的共聚物电介质赋予柔性OTFT高迁移率（5.6 cm2V−1s−1）、低工作电压（3 V）和出色的稳定性。进一步验证了它们在集成电路中的适用性。优异的器件性能显示了这种分子尺度工程共聚物在实现塑料高性能集成电子学方面的令人兴奋的前景。
The ever-increasing demand for flexible electronics calls for the development of low-voltage and high-mobility organic thin-film transistors (OTFTs) that can be integrated into emerging display and labeling technologies. Polymer dielectrics with comprehensive and balanced dielectric properties (i.e., a good balance between their insulating characteristics and compatibility with organic semiconductors) are considered particularly important for this end. Here, we introduce a simple but highly efficient strategy to realize this target by using a new type of copolymer as dielectrics. Benefiting from both high chain packing density guaranteeing dielectric properties and surface polarity optimizing molecular packing of organic semiconductors, this rationally designed copolymer dielectric endows flexible OTFTs with high mobility (5.6 cm2V−1s−1), low operating voltage (3 V) and outstanding stability. Further, their applicability in integrated circuits is verified. The excellent device performance shows exciting prospects of this molecular-scale engineered copolymer for the realization of plastic high-performance integrated electronics.
