Boron dipyrromethenes (BODIPYs) are versatile dyes with diverse structures and associated optoelectronic properties. Their integration into soft materials (polymers) has enabled a myriad of applications from biological/environmental (e.g., imaging, sensing, and therapy) to organic electronic devices and synthesis/degradation. The story herein is meant to guide the reader from the bottom-up, starting with general syntheses of BODIPYs, followed by a discussion of photophysical and electrochemical properties as they relate to structure. These structure–property relationships are then connected to three light driven transformations that are central to the utility of BODIPYs in materials science: (1) electron/energy transfer; (2) triplet formation, and (3) photolysis. Next, the synthetic integration of BODIPYs as structural motifs in both π-conjugated and non-π-conjugated polymers is described, along with prescribed methods to tailor their optoelectronic properties. These properties are then correlated to recent utility of BODIPYs within polymer science, both fundamental – examination of polymer dynamics and self-assembly – and applied – biomedicine, optoelectronics, chemosensors, small molecule photoredox catalysis, and photo-polymerization and -degradation. The end of this review provides a summary of the rich history and outlook on the exciting future opportunities for this burgeoning field of BODIPYs in polymer chemistry.

聚合物化学中的硼二吡咯亚甲基（BODIPY）

硼二茂铁（BODIPYs）是具有多种结构和相关光电性能的通用染料。它们与软质材料（聚合物）的结合已经实现了生物/环境（例如，，成像，传感和治疗）到有机电子设备以及合成/降解。本文的故事旨在从下至上引导读者，从BODIPY的一般合成开始，然后讨论与结构有关的光物理和电化学性质。然后将这些结构-属性关系与三个光驱动转换相关联，这三个转换对BODIPY在材料科学中的应用至关重要：（1）电子/能量转移；（2）三重态形成，和（3）光解。接下来，描述了将BODIPYs作为结构共轭体在π共轭和非π共轭聚合物中的合成整合，以及调整其光电性能的规定方法。然后将这些属性与BODIPY在聚合物科学领域的最新应用相关联，包括聚合物动力学和自组装的基础研究，以及生物医学，光电，化学传感器，小分子光氧化还原催化以及光聚合和降解等方面的应用。这篇综述的结尾部分总结了BODIPY在聚合物化学这个新兴领域令人兴奋的未来机遇的丰富历史和前景。
