In 2024, the global data storage industry is predicted to be valued at more than one hundred billion dollars. The technology that currently underpins data storage is based on the memory properties of relatively large magnetic particles: society's need to handle increasingly large amounts of data whilst decreasing the physical size of the storage medium necessitates the discovery of innovative storage methods.Using sub-nanometre molecules to store magnetic information introduces potential for developing data storage materials that could out-perform conventional technology, responding to the needs of a data-intensive world. The big problems are that the best magnetic molecules available for this challenge function at extremely low temperatures and they decompose on contact with air. We now propose to solve both problems by combining world-leading capability in synthetic chemistry with unique physics expertise and instrumentation in a highly adventurous New Horizons project. By developing a novel approach to making and measuring molecular magnetic materials, we aim to chart a flexible path to the early-stage fabrication of nanoscale magnetic devices based on an unprecedented type of metal-organic composite material, which will consist of single-molecule magnets and metal-organic frameworks, or SMM@MOF materials.We will also undertake proof-of-concept experiments aimed at preparing thin films of selected SMM@MOF composites. Should we show that SMM@MOF thin films have magnet-like behaviour, the results will form the basis of future research aimed at the fabrication of molecule-based magnetic devices. Success with this project will help to drive the second quantum revolution and provide a platform on which to discover innovative quantum technologies.

2024年，预计全球数据存储行业的价值将超过10亿美元。目前基于数据存储的技术基于相对较大的磁性颗粒的内存特性：社会需要处理越来越多的数据，同时降低了存储介质的物理尺寸的必要性，需要发现无效的存储方法。使用无纳米分子来存储磁性信息，以使能够开发数据的潜在磁性信息，从而超越了常规技术，这可能会响应于常规的技术。最大的问题是，在极低的温度下可用于此挑战功能的最佳磁性分子，并且在与空气接触时分解。现在，我们建议通过将合成化学中的世界领先能力与独特的物理专业知识和仪器相结合，以解决这两个问题。通过开发一种新型的制造和测量分子磁性材料的方法，我们旨在为基于前所未有类型的金属有机复合材料的纳米级磁性设备的早期制造绘制一条灵活的途径，该材料将由单分子磁体和金属有机框架组成，并在smm@@mof@@mof@@mof@@mof@@@mof@@@mof@@@@mof。复合材料。如果我们证明SMM@MOF薄膜具有类似磁性的行为，则结果将构成针对基于分子的磁性设备制造的未来研究的基础。该项目的成功将有助于推动第二个量子革命，并提供一个平台，以发现创新的量子技术。
