在设计、合成功能分子基元的基础上,综合考虑能量、结构和性质匹配的原则及小尺度下复杂的物理化学现象等关键科学问题,建立了自组装新方法,发展了尺寸与结构可控的分子聚集态结构材料定向、定维自组装技术,构建了大面积、高有序分子聚集态结构材料.并研究了有序异质和同质结构以及表界面问题,特别是界面活性、界面连接等关键科学问题.证明了分子聚集态材料中的性质和性能与形貌、尺寸和维数的强烈依赖关系.从合成化学新的视角出发,建立了合成碳的新同素异形体——石墨炔的新方法,并研究了石墨炔在信息技术、电子、能源、催化以及光电等领域的应用.这些研究对化学、材料科学、物理学、微电子学等基础科学研究以及基于这些学科的交叉研究具有重大的科学意义.
On the basis of the design and synthesis of functional molecules, considering the key scientific issues of energy principle, match between structure and properties, and complex physical and chemical phenomena at small-scale, the new self-assembly methods were established to develop self-assembly techniques for molecular aggregation materials with controllable sizes and structures, and some large area, highly ordered molecular aggregation materials were constructed. Ordered heterogeneous and homogeneous materials and surface/interface issues, especially interface activity, interface connecting were investigated. The strong dependence of property and functionality on the morphology, size and dimension in the molecular aggregation materials was proved. The synthesis method for a new allotrope of carbon, graphydiyne, was established, the first successful synthesis of two-dimensional carbon allotrope graphydiyne with band gap of 0.46 eV on the copper foil was achieved, and the application of graphydiyne in the area of information technology, electronics, energy, catalysis and photovoltaic were investigated. These studies are of great scientific significance on chemistry, materials science, physics, rnicroelectronics and other basic scientific research and related interdisciplinary areas, showing important academic value and potential applications in the area of micro-nano electronics, field emission, photoelectric conversion and biosensors.
