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.

分子电子学正在成为一个强大的技术平台，是一个被认为是欧洲最近在科学方面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吸引人的可能性。分子的重要优点是它们在电子性质、尺寸和通过自组装技术获得自组装单层（SAM）或功能域的组织设计方面的多功能性。在这些纳米结构中，可以将联合收割机有源电子部件与无源电子部件组合，例如具有绝缘体的电子导体，或者具有不同折射率的分子组件用于光导模式。特别令人感兴趣的是使用超分子和超分子自组织结构的装置的开发，其中单个分子组分的有限功能通过它们组织成更大的超分子系统而增强。尽管超分子和超分子化学领域取得了快速的进展，包括氧化还原开关和光驱动分子机器的演示，但令人惊讶的是，在该领域的技术应用实例仍然很少。缺乏对这种复杂架构的技术开发背后有两个关键因素。首先，尽管超分子结构的增强功能性已经在溶液中得到广泛证实，但是迄今为止，将这种超分子结构集成到固态电子或光电器件中非常有限。其次，更重要的是，人们对分子实体与自组织材料结构之间的关系以及它在分子电子器件中的作用仍然缺乏基本的了解。这些问题的根本利益和必不可少的“下一代”分子电子和异质超分子器件的发展。该项目旨在解决这些问题，并研究在定义明确的纳米结构组件中产生的光学和电学现象。我们的目标是探索这些纳米结构组件在电子器件应用中的潜力，如太阳能电池，场效应晶体管和发光二极管。为了实现这一目标，我们将进行一个多学科的研究计划，包括新型纳米材料的合成，功能表征（基于激光的光泵浦光谱），以及电子器件的制造和测试。
