Our research group will address questions at the forefront of the rapidly developing and extremely important field of multifunctional materials for data processing and storage. Recent developments were triggered, in part, by new discoveries made in our laboratory related to the ability to change the magnetic state of organic molecular materials by light radiation, and modulate conductivities and magnetic properties by tuning the structures of pi-conjugated radicals. Our studies of photochromic organic metal complexes as well as our recent experiments with conjugated molecules and polymers (like those used in plastic solar cells and displays) suggest that it is possible to achieve control using light or charge state even under room temperature conditions. This is striking because previous research suggested that optical or charge control in multifunctional materials could only be achieved at very low temperatures. With the knowledge of how to synthesize and characterize our molecular materials, the new experiments will elucidate the structural parameters that dictate optical and charge control. The long term goal is to develop new multifunctional materials and devices for electronics and data storage that require low turn on and operation voltages as part of the global mandate for green information technology (green IT).

我们的研究小组将解决迅速发展和极为重要的多功能材料领域的问题，用于数据处理和存储。在我们的实验室中发现的新发现触发了最新的发展，这与通过光辐射改变有机分子材料的磁状态的能力以及通过调节PI偶联自由基的结构来调节电导率和磁性的能力。我们对光致动物有机金属络合物以及最近对共轭分子和聚合物的实验（如塑料太阳能电池和显示器中使用的实验）表明，即使在室温下，也可以使用光或电荷状态实现对照。这是令人惊讶的，因为先前的研究表明，只有在非常低的温度下才能实现多功能材料中的光学或电荷控制。 了解如何合成和表征我们的分子材料，新实验将阐明决定光学和电荷控制的结构参数。长期目标是为电子和数据存储开发新的多功能材料和设备，这些材料和数据存储需要较低的打开和操作电压，这是绿色信息技术（Green IT）全球任务的一部分。
