π‐Conjugated polymers have drawn broad interest in flexible electronics due to their solution processability, light weight, and a combination of conducting and light‐emitting properties. However, achieving mechanical endurance and stretchability in freestanding conjugated polymers is still difficult. Surface‐assembly‐induced light‐emitting polymer nanosheets with prodigious mechanical strength and charge transport are reported. Transferring freestanding polymer films onto various templates with conformal contact results in electrical and optical strain sensors with a gauge factor of ≈29. Subsequent geometric engineering into kirigami structures of the polymer sheets further extends the strain accommodations 20‐fold without compromising electric conductivity or fluorescence properties. These as‐prepared semiconducting polymers represent a possible new material for emerging stretchable electronics.

受Kirigami启发的可拉伸共轭电子

π共轭聚合物因其溶液的可加工性，重量轻以及导电和发光特性的结合而在柔性电子领域引起了广泛的关注。然而，在独立的共轭聚合物中实现机械耐久性和可拉伸性仍然是困难的。据报道，表面组装诱导的发光聚合物纳米片具有出色的机械强度和电荷传输能力。将独立的聚合物膜以保形接触的形式转移到各种模板上，会产生电应变和光学应变传感器，其应变系数约为29。随后对聚合物片的折纸结构进行几何工程设计，将应变适应性进一步扩展了20倍，而不会损害导电性或荧光特性。
