Magnets are ever-present in our society and have shaped the technological development of our culture. There are literally thousands of applications of magnetic materials: They are found in motors and generators (an automobile engine contains over 20 magnets), in medical devices (such as MRI technology) and implants, in telecommunication and radar technology and we use magnetic materials to store our data on our computer hard drives. We are interested in the preparation of new molecular magnetic materials. These are different from the magnets most people are familiar with, like iron oxide or nickel. We propose to make extremely small magnets-on the scale of single molecules. As chemists we study the structure and properties of matter: we are also engaged in the preparation of new matter by a process called chemical synthesis. Most traditional magnets have properties that make the manipulation of their structure very difficult or impossible. On the other hand, synthetic chemists are able to alter molecular structures. If we can build magnets based on molecular precursors, we have the opportunity to tune the properties of our materials with our synthetic manipulations. In this way, we can create magnets with unprecedented properties: Liquid magnets or plastic magnets are just a couple of the many exciting possibilities. In fact, we hope to use these materials for future applications in magnetic data storage media or as new sensory devices. We expect our materials to tremendously increase computer data storage capacities and processor speeds in the future, in addition to a number of other exciting applications.

磁铁在我们的社会中无处不在，并塑造了我们文化的技术发展。 磁性材料有成千上万的应用：它们被发现在电动机和发电机（汽车发动机包含20多个磁铁），医疗设备（如MRI技术）和植入物，电信和雷达技术中，我们使用磁性材料将数据存储在计算机硬盘上。 我们对新型分子磁性材料的制备很感兴趣。 这些磁铁不同于大多数人熟悉的磁铁，如氧化铁或镍。 我们打算制造极小的磁铁--在单分子的尺度上。 作为化学家，我们研究物质的结构和性质：我们还通过一种称为化学合成的过程来制备新物质。 大多数传统磁体具有使其结构的操纵非常困难或不可能的特性。 另一方面，合成化学家能够改变分子结构。 如果我们能够基于分子前体构建磁体，我们就有机会通过合成操作来调整材料的特性。 通过这种方式，我们可以制造出具有前所未有特性的磁体：液体磁体或塑料磁体只是许多令人兴奋的可能性中的一部分。 事实上，我们希望将这些材料用于磁性数据存储介质或作为新的传感设备的未来应用。 我们希望我们的材料在未来能够极大地提高计算机数据存储容量和处理器速度，以及许多其他令人兴奋的应用。
