SONSEUROCORES - Self Organised Hybrid Devices (SOHYD)

分子电子学正在成为一个强大的技术平台，也是一个被公认为欧洲最近在科学领域取得成功的领域之一。它结合了当今电子学和光电子学的许多属性，具有在分子水平上控制功能的诱人可能性。分子的重要优点是它在设计电子性质、尺寸和通过自组装技术来组织它们获得自组装单分子膜(SAM)或功能域方面具有多功能性。在这些纳米结构中，人们有可能将有源电子元件和无源电子元件结合在一起，例如带有绝缘体的电子导体，或者具有不同折射率的光导模式的分子组件。特别令人感兴趣的是使用超分子和超分子自组织结构的设备的开发，其中单个分子组件的有限功能通过它们组织成更大的超分子系统来增强。尽管在超分子和超分子化学领域取得了迅速的进展，包括展示了氧化还原开关和光驱动分子机，但令人惊讶的是，这一领域的技术应用实例仍然很少。缺乏对这种复杂体系结构的技术开发背后有两个关键因素。首先，虽然超分子结构的增强功能在溶液中得到了广泛的展示，但到目前为止，将这种超分子结构集成到固态电子器件或光电子器件中的研究还非常有限。其次，更重要的是，人们对分子实体和自组织材料的结构以及它在分子电子器件中的功能仍然缺乏基本的了解。这些问题对“下一代”分子电子器件和杂化超分子器件的发展至关重要。该项目将致力于解决这些问题，并研究在定义良好的纳米结构组件中出现的光学和电学现象。我们的目标是探索这些纳米结构组件在太阳能电池、场效应晶体管和发光二极管等电子设备应用中的潜力。为了将这一目标变为现实，我们将开展一项多学科研究计划，涉及新型纳米材料的合成、功能表征(基于激光的光学泵浦光谱学)以及电子器件的制造和测试。

Molecular electronics is emerging as a powerful technology platform and is an area that is recognised as one of the recent European success stories in science. It combines many of the attributes of present day electronics and optoelectronics with attractive possibilities for control of functionality at the molecular level. Important advantages of molecules are their versatility in design of electronic properties, their dimensions, and their organization by self-assembling techniques to obtain self-assembled monolayers (SAMs) or functional domains . In these nanostructures one has the possibility to combine active electronic components with passive ones as for example electronic conductors with insulators, or molecular assemblies with different refractive indexes for light guiding modes . Of particular interest is the development of devices using supra- and super-molecular self-organized architectures, where the limited functionalities of individual molecular components are enhanced by their organization into larger super molecular systems. Although, rapid progress has been made in the fields of supra molecular and super molecular chemistry, including the demonstrations of redox switches and light driven molecular machines it is striking that there are still only few examples of technological applications in this field . There are two key factors behind the lack of technological exploitation of such complex architectures. Firstly, whilst enhanced functionality of super molecular structures has been widely demonstrated in solution, the integration of such super molecular structures into solid state electronic or optoelectronic devices has been very limited to date . Secondly, and more importantly, there still remains a basic lack of understanding between the molecular entity and the self-organized materials structure, as well as its function in molecular electronic devices. These issues are of fundamental interest and essential to the development of 'next generation' molecular electronic and hetero supra molecular devices. This project will aim to address these issues and investigate optical and electrical phenomena arising in well defined nano-structured assemblies. We aim to explore the potential of these nanostructured assemblies in electronic device applications such as solar cells, field-effect transistors and light emitting diodes. To turn this aim into reality we will conduct a multidisaplinary research program involving novel nanomaterials synthesis, functional characterization (laser based optical pump-prope spectroscopy), and electrical device fabrication and testing.
