摘　　要：可拉伸高分子光电器件是一类基于共轭高分子的独特器件,具备在承受机械应变时仍能维持其光电性能的能力,在可穿戴电子、可拉伸显示、生物医学传感等领域展现出广阔的应用潜力.近年来,国内外学者对器件与材料设计进行了大量的探索,为其性能提升和应用拓展奠定了坚实基础.本文以外在弹性与本征弹性2个维度为切入点,深入探讨器件形态设计、材料结构调控以及薄膜组分优化等策略,总结并评述其重要成果.最后,指出未来需要关注的重点研究方向,以克服商业化过程中面临的多重挑战,并展望可拉伸高分子器件的不断进步能为有机电子领域注入新的活力.Stretchable polymer optoelectronic devices,as a unique class of devices based on conjugated polymers,are capable of maintaining their optoelectronic performance under mechanical deformations.Such unique feature gives them significant potential in applications such as wearable electronics,stretchable displays,biomedical sensing and beyond.In recent years,extensive research both domestically and internationally in device and material design has laid the groundwork for enhancing the performance and expanding the applications of these devices.Currently,stretchable optoelectronic devices are primarily constructed by two approaches:external elasticity and intrinsic elasticity. Devices using external elasticity achieve stretchability through specific device forms, such as wrinkle structures, “island-bridge” structures, fiber structures, and kirigami structures. In contrast, devices based on intrinsic elasticity achieve stretchability in each functional layer through thin film modifications, such as molecular design, blending with elastomers, and adding plasticizers. This review delves into these two construction methods, examining strategies for device design, chemical modification, and thin-film composition optimization. It reviews significant research achievements in organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), organic photovoltaic cells (OPVs), and organic photodetectors (OPDs). Finally, the paper points out key research directions, highlighting challenges and opportunities in material and film modification, device engineering, and studies on structure-performance relationship. It envisions that the ongoing development of stretchable polymer optoelectronic devices will bring new vitality and breakthroughs to the field of organic electronics.
