项目摘要

1.The human being has highly sensitive and flexible five senses such as eye, nose, ear and so on. One of the important subjects is to mimic these functions as functionally harmonized artificial materials. We successfully created novel functional sensor/memories by combining inorganic/organic/bio-materials, which can be applicable to highly sensitive and multi-functional devices that respond to a variety of external fields.2.The novel artificial photosynthetic material was developed as one of solutions in a food shortage problem and an environmental issue. A photosynthetic material is recognized as a well-sophisticated highly function harmonized material combined by photo-absorption, electron transfer, reduction/oxidation reactions and so on. We achieved this propose by synthesis of novel donor/acceptor compounds and formation of their monolayer on the metal substrate.3.We developed an atomic/molecular layer deposition technique and a crystal growth technique in nano scale area, such as molecular beam epitaxy and laser-molecular beam epitaxy, to successfully construct function harmonized superstructures among semiconductor, metal and organic materials.4.We created bio-adaptable nano-materials unifying mechanical and chemical functionalities, such as the nano-composite artificial born.5.We constructed a knowledge data base assisted material deign on the base of our new concept, and established a guiding principle of material design based on first principle quantum simulations leading to discovery of new materials.

1.人类具有高度敏感和灵活的眼睛、鼻子、耳朵等五种感官。其中一个重要的课题是将这些功能模拟为功能协调的人造材料。我们通过将无机/有机/生物材料相结合，成功地创造了新型的功能传感器/存储器，可以应用于对各种外场响应的高灵敏度和多功能设备。2.新型人工光合作用材料被开发出来，作为解决粮食短缺问题和环境问题的方案之一。光合作用物质是一种通过光吸收、电子传递、还原/氧化反应等过程结合而成的复杂的、高功能的配位材料。3.发展了原子/分子层沉积技术和纳米尺度的晶体生长技术，如分子束外延和激光-分子束外延，成功地构建了半导体、金属和有机材料之间的功能协调超结构。4.我们创造了集机械和化学功能于一体的生物适应性纳米材料，如纳米复合材料人工晶体。5.在我们新概念的基础上，建立了辅助材料设计的知识库，并建立了基于第一性原理量子模拟的材料设计指导原则，导致了新材料的发现。
