Functional polymers have transformed, and continue to revolutionize, the materials landscape in monumental manners such that these advanced systems are put into critical products across a plethora of application arenas. Moreover, the field of polymer electronics has seen rapid and sustained growth over the last 30 years such that fundamental advances regarding the polymer chemistry and polymer physics of these macromolecules have led to transformational technologies. However, a related field has seen less attention, and that is the study of magnetic and spin-active polymers. While some research teams have made impressive strides in the realm of soft materials, the majority of the community has focused on inorganic and two-dimensional (2D) materials. In this Collection, we aim to (a) highlight recent publications in ACS Macro Letters that demonstrate the impressive foundational principles of the materials; (b) offer a means by which to introduce the broader readership to this area of study; and (c) encourage the community to submit their work to this effort such that the most exciting related research results are archived in a cohesive manner. We very much thank the American Chemical Society and the editorial team of ACS Macro Letters for providing us with an opportunity to facilitate the creation of a Collection that we anticipate will alter the polymer science arena. In this Collection, we have intentionally opened two distinct, but related, fields associated with the magneto-responsive and spin-responsive behavior of macromolecular systems. While the materials design paradigms for enhanced performance in either of these end-use spaces is distinct, there are clear points of synergy in coupling these avenues of research. Importantly, this Collection aims to stress the foundational principles associated with the chemistry, physics, and materials science of the polymers. While it is not unlikely that the structure–property relationship formulation could involve device fabrication and testbed characterization, works in this Collection will not include manuscripts whose primary intellectual merit is centered on device fabrication or performance optimization. Instead, we turn to the community to submit efforts that address underlying points regarding topics such as, but not limited to, (a) advanced archetypes for the synthesis of magnetic- and spin-active polymers; (b) the thermal, structural, and end-use properties of next-generation materials based on these macromolecules; (c) efforts that elucidate the unique interactions that arise due to coupling of polymers and magnetic fields; and (d) reports that detail the mechanism of spin transport in polymers. Addressing foundational questions such as these will continue to speed the progress in this exciting field that is building from a solid foundation, but a foundation that has significantly less literature associated with it than traditional organic electronics and polymer-based energy conversion and energy storage materials. In this context, we envision the following exemplary cases will encourage active discussion among disciplines, altogether expediting the advancement of such functional polymers in a constructive manner. These include molecular design and engineering strategies centered on spin-active and magnetic polymers, as highlighted by Delage-Laurin et al. in their work on the effectiveness of Faraday rotation and magneto-optical properties of polyferroceniums. (1) Similarly, the synthetic efforts recently made by Malech et al. and Alvaradejo et al. on the ring-opening metathesis of magnetic and/or spin monomers highlight how molecular design and advanced synthesis are critical to this community. (2,3) Another focus of this Collection is the structure–property relationship in spin and magnetic polymers. This is well exemplified by the recent work of Yu et al., which addressed the impact of structural variations on the paramagnetic or antiferromagnetic behavior of (poly)magnetic ionic liquids. (4) Additionally, Chan et al. and Costa et al. described the structural effects through the self-assembly of micellar nanoparticles in the development of diblock copolymers with pendant persistent organic radicals for magnetic resonance imaging (MRI) contrast agents. (5,6) Of course, we also encourage manuscripts based on theory and/or computation, as previous efforts have highlighted the power of these scholarly activities for the field. (7) By using this Collection as a means by which to pull the community together at this critical stage, we envision the rapid growth of the field over the next five years. That is, there is no reason why the growth trajectory of materials and applications associated with magnetic- and spin-active polymers cannot be on an even greater ascent than what occurred with electronic (e.g., conjugated) polymers and applications over the last three decades. This is because, in addition to the oft-recited advantages of solution-processable, low-cost polymer materials in the organic electronics regime, there are foundational material properties associated with soft polymeric materials that make them attractive relative to their inorganic counterparts for magnetic and spin applications. Thus, it is not a question of whether these materials will make significant inroads into applications such as quantum systems; instead, it is a question of the timing based on the appetite of the community to rally around these emerging materials and physics to speed the development in a deliberate manner. This Collection has that ability to initiate that steep climb. With this overarching point in mind, we also strongly encourage advanced data sharing efforts for manuscripts submitted to this effort such that the data and metadata associated with these publications are consistent with the findable, accessible, interoperable, and reusable (FAIR) principles. This open sharing of data will both allow for rapid validation of principles from other research teams and speed the development of the materials and principles using a combined computational and experimental approach. In this way, there is a wonderful opportunity for the community to rally for impressive and immediate impact to set the tone of science for this field. The organic electronics community historically has been one that brings together researchers from across the chemistry, physics, materials science, engineering, and biotechnology disciplines. Thus, the interdisciplinarity of the scientists and engineers that will push this exciting field forward is already established. History has shown that, as end-use applications have moved from transistors and light-emitting devices to energy conversion and energy storage systems and on to biomedical devices, the creativity and collaborative nature of folks in this polymer science arena is unlimited. Here, we applaud the researchers who have already taken the next step in this field, and we celebrate those who will contribute to this Collection through their own advancements and research accomplishments.

自旋活性和磁性聚合物


功能聚合物已经并继续以巨大的方式改变材料格局，使得这些先进的系统被应用于众多应用领域的关键产品中。此外，聚合物电子领域在过去 30 年中经历了快速且持续的增长，使得这些大分子的聚合物化学和聚合物物理的根本性进步带来了变革性技术。然而，一个相关领域却很少受到关注，那就是磁性和自旋活性聚合物的研究。虽然一些研究团队在软材料领域取得了令人印象深刻的进步，但大多数研究团队都专注于无机和二维 (2D) 材料。在本合集中，我们的目标是 (a) 重点介绍 ACS Macro Letters 中最近发表的出版物，这些出版物展示了这些材料令人印象深刻的基本原则； (b) 提供一种向更广泛的读者介绍这一研究领域的方法； (c) 鼓励社区将他们的工作提交给这项工作，以便以一致的方式归档最令人兴奋的相关研究成果。我们非常感谢美国化学会和 ACS Macro Letters 的编辑团队为我们提供了一个机会来促进创建一个集合，我们预计该集合将改变聚合物科学领域。在本系列中，我们有意打开了两个不同但相关的领域，这些领域与大分子系统的磁响应和自旋响应行为相关。虽然在这两个最终用途空间中增强性能的材料设计范例是不同的，但在耦合这些研究途径时存在明显的协同点。 重要的是，该系列旨在强调与聚合物的化学、物理和材料科学相关的基本原理。虽然结构-性能关系公式不太可能涉及器件制造和测试台表征，但本集合中的作品将不包括主要智力价值集中于器件制造或性能优化的手稿。相反，我们转向社区提交解决有关主题的基本观点的努力，例如但不限于（a）用于合成磁性和自旋活性聚合物的先进原型； (b) 基于这些大分子的下一代材料的热、结构和最终使用特性； (c) 努力阐明由于聚合物和磁场耦合而产生的独特相互作用； (d) 详细介绍聚合物中自旋输运机制的报告。解决诸如此类的基础问题将继续加速这个令人兴奋的领域的进展，该领域建立在坚实的基础上，但与传统有机电子和基于聚合物的能量转换和储能材料相比，与之相关的文献要少得多。在此背景下，我们预计以下典型案例将鼓励学科之间的积极讨论，共同以建设性的方式加速此类功能聚合物的进步。正如 Delage-Laurin 等人所强调的，其中包括以自旋活性和磁性聚合物为中心的分子设计和工程策略。他们对法拉第旋转的有效性和聚二茂铁磁光特性的研究。 (1) 同样，Malech 等人最近做出的综合努力。 和阿尔瓦拉德霍等人。关于磁性和/或自旋单体的开环复分解强调了分子设计和高级合成对于该领域的重要性。 (2,3) 该系列的另一个重点是自旋和磁性聚合物的结构-性能关系。 Yu等人最近的工作很好地证明了这一点，该工作解决了结构变化对（多）磁性离子液体的顺磁或反铁磁行为的影响。 (4) 此外，Chan 等人。和科斯塔等人。描述了在开发用于磁共振成像（MRI）造影剂的带有持久性有机自由基的二嵌段共聚物时，通过胶束纳米粒子的自组装产生的结构效应。 (5,6) 当然，我们也鼓励基于理论和/或计算的手稿，因为之前的努力已经强调了这些学术活动对该领域的力量。 (7) 通过使用这个集合作为在这个关键阶段将社区团结在一起的手段，我们预计该领域在未来五年内将快速发展。也就是说，过去三十年来，与磁性和自旋活性聚合物相关的材料和应用的增长轨迹没有理由不能比电子（例如共轭）聚合物和应用的增长轨迹更大。这是因为，除了在有机电子领域中经常提到的可溶液加工、低成本聚合物材料的优点之外，软聚合物材料还具有与软聚合物材料相关的基本材料特性，这使得它们相对于无机材料在磁性和磁性方面具有吸引力。旋转应用程序。 因此，问题不是这些材料是否会在量子系统等应用中取得重大进展；而是这些材料是否会在量子系统等应用中取得重大进展。相反，这是一个基于社区意愿的时机问题，围绕这些新兴材料和物理学聚集在一起，以刻意的方式加速发展。该系列具有启动陡峭攀登的能力。考虑到这一点，我们还强烈鼓励对提交给这项工作的稿件进行先进的数据共享工作，以便与这些出版物相关的数据和元数据符合可查找、可访问、可互操作和可重用 (FAIR) 原则。这种数据的开放共享既可以快速验证其他研究团队的原理，也可以使用计算和实验相结合的方法加速材料和原理的开发。通过这种方式，社区就有了一个绝佳的机会来团结起来，产生令人印象深刻和直接的影响，从而为该领域的科学定下基调。有机电子学界历来是一个汇集了来自化学、物理学、材料科学、工程和生物技术学科的研究人员的社区。因此，推动这一令人兴奋的领域向前发展的科学家和工程师的跨学科性已经建立。历史表明，随着最终用途应用从晶体管和发光器件转向能量转换和能量存储系统，再到生物医学设备，人们在这个聚合物科学领域的创造力和协作性是无限的。 在此，我们赞扬那些已经在这一领域迈出下一步的研究人员，并庆祝那些将通过自己的进步和研究成就为这个集合做出贡献的人。本文参考了其他 7 篇出版物。这篇文章尚未被其他出版物引用。本文参考了其他 7 篇出版物。
