本文综述了包含刚性棒状嵌段和柔性线圈状嵌段的棒-线圈嵌段共聚物（BCP）研究领域的最新进展。由于杆和线圈段之间的几何差异以及杆块之间形成液晶或晶体结构的各向异性相互作用，它们的组装行为在形态上与线圈-线圈 BCP 有根本不同。棒状线圈 BCP 可以在选择性溶剂中自组装成多种纳米结构，例如胶束、圆柱体、囊泡、管状、带状和环状。本综述重点介绍了过去六年中从实验和理论角度对由体积分数和块体组成控制的棒线圈 BCP 自组装行为及其由外部刺激（如溶剂、pH、温度、光和化学添加剂）触发的可调谐自组装纳米结构的宝贵贡献。我们还简要介绍了棒状线圈纳米颗粒在生物领域的新兴应用。
This review covers the recent progress in the research field of rod-coil block copolymers (BCPs) containing rigid rod-like blocks and flexible coil-like blocks. Their assembly behaviors are fundamentally different from coil-coil BCPs in morphology because of the geometric disparity between the rod and coil segments and anisotropic interactions between rod blocks to form liquid crystalline or crystalline structures. Rod-coil BCPs can self-assemble into diverse nanostructures in selective solvents, such as micelles, cylinders, vesicles, tubules, belts, and rings. This review highlights valuable contributions in the past six years on the self-assembly behavior of rod-coil BCPs controlled by the volume fraction and the composition of the blocks from both the experimental and theoretical perspectives, and their tunable self-assembled nanostructures triggered by external stimuli, such as solvent, pH, temperature, light, and chemical additives. We also briefly introduce emerging applications of rod-coil nanoparticles in the biological field.
