项目摘要

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.

预计到2024年，全球数据存储产业价值将超过千亿美元。目前支持数据存储的技术基于相对较大的磁性粒子的存储特性：社会需要处理越来越多的数据，同时减小存储介质的物理尺寸，因此需要发现创新的存储方法。使用亚纳米分子存储磁性信息带来了开发数据存储材料的潜力，这些材料可以超越传统技术，满足数据密集型世界的需求。最大的问题是，应对这一挑战的最佳磁性分子在极低的温度下起作用，并且在与空气接触时分解。我们现在建议通过高度冒险的新视野项目将世界领先的合成化学能力与独特的物理专业知识和仪器相结合来解决这两个问题。通过开发一种制造和测量分子磁性材料的新方法，我们的目标是为基于前所未有的金属有机复合材料（由单分子磁体组成）的纳米级磁性器件的早期制造开辟一条灵活的途径和金属有机框架，或SMM@MOF材料。我们还将进行概念验证实验，旨在制备选定的SMM@MOF复合材料的薄膜。如果我们证明 SMM@MOF 薄膜具有类似磁铁的行为，那么结果将成为未来制造基于分子的磁性器件的研究的基础。该项目的成功将有助于推动第二次量子革命，并为发现创新量子技术提供一个平台。
