中文摘要: 青年基金中,针对目前溶液中逻辑分子不易控制的问题,我们提出了在纳米线表面组装逻辑分子构建逻辑器件的模式。通过在硅纳米线和氧化锌纳米线阵列表面组装单一功能逻辑分子,实现了基于纳米线阵列的多态逻辑光开关,到目前为止,已经发表SCI论文13篇,申请发明专利6项。在此基础上,为解决不同功能逻辑分子在纳米线阵列的集成问题,实现集成度更高的分子逻辑器件,本项目拟开展不同功能逻辑分子在同一硅纳米线阵列表面的组装,实现多态多功能逻辑器件的集成。主要内容包括硅纳米线阵列的可控制备及表面调控;设计、合成不同功能的逻辑分子,并将其同时组装在硅纳米线阵列表面;研究功能分子的结构及表面修饰密度对多功能逻辑开关阈值的影响,实现在纳米线阵列上构建多态多功能逻辑器件;进一步发展逻辑器件在传感方面的应用,实现多目标的相关联检测。本项目的研究结果将为制备集成化程度更高、性能更好的分子逻辑运算器件提供重要的实验和理论依据。

英文摘要: In order to solve the present problem---poor control of logic molecules in solution, we presented the model of building logic devices by assemblying logic molecules on surface of nanowire in proposal of Youth Foudation. Multi-state logic optical switches were realized by grafting logic molecules on surface of silicon and zinc oxide nanowire arrays. These results have been collated into 13 papers (SCI) and 6 Chinese patents. In this proposal, we intend to realize the higher integration of molecular logic devices. The research includes: controllable preparation of the silicon nanowire arrays; designs and syntheses of optically functional logic molecules; the relevance between structures of logic molecules, assemblying density on surface of nanowire and the threshold of logic switches; assemblying different logic molecules on the surface of the nanowire arrays to configure the multi-state logic devices; application of logic devices in sensing to achieve detection of multiple goals. The proposal will provide an important experimental and theoretical basis for preparation of molecular logic devices with smaller and a higher degree of integration.
