I have studied on the self-assembly metal complexes with the multidentate Schiff base ligand involving an imidazole moiety. My metal complex behaves itself like a simple building block and exhibits the following characteristics (1) the complex has potentially donor coordination ability at the imidazolate nitrogen ; (2) the complex has potentially acceptor coordination ability at the vacant or substitutable coordination site ; (3) Although the complex has potentially both donor and acceptor coordination ability, either or both of two abilities is absent under the pH region lower than the pK_H. When the proton is dissociated under the pH higher than the pK_H, donor and acceptor coordination ability appear and the self-assembly process is promoted. In this system, a construction processes from isolated molecules to assembled molecule and the reverse deconstruction processes are both available by inputting external information such as pK_H ; (4) The resulting assembled molecular structure would be determined cooperatively by ligand framework and metal ion, because the ligand framework can give a steric restriction and metal ion assumes its preferable coordination geometry.

我研究了含有咪唑基团的多齿希夫碱配体的自组装金属配合物。我的金属配合物表现得像一个简单的构建块，并表现出以下特征：(1)配合物在咪唑氮上具有潜在的供体配位能力；(2)配合物在空位或可取代的配位位点具有潜在的受体配位能力；(3)虽然该配合物具有潜在的供体配位能力和受体配位能力，但在pH值低于pK_H的区域，这两种能力都不存在。当质子在高于pK_H的pH下解离时，供体和受体的配位能力出现，并促进了自组装过程。在该系统中，通过输入pK_H等外部信息，可以实现从孤立分子到组装分子的构建过程和逆向解构过程；(4)由于配体框架具有空间限制作用，金属离子具有较好的配位几何形状，因此组装后的分子结构由配体框架和金属离子共同决定。
