摘　　要：近年来,以生物分子作为配体连接金属离子形成的多孔材料金属-生物分子框架配合物(MBio Fs)受到广泛的关注,并成为配位化学与生物材料科学之间新的交叉学科。作为核酸的核心组分的核酸碱基,拥有氮、氧孤对电子,使其可以作为多齿配体。我们用溶剂热法以不同的核酸碱基合成了一系列的金属-生物分子框架配合物。由于桥连配体核酸碱基配位性质的不同,这些金属-生物分子框架配合物表现出不同的微观结构。此外,它们可以周期性的吸收和释放有机物分子,因此可以用于污水处理。Metal-biomolecule frameworks （MBioFs） are a recently-identified class of porous polymeric materials, consisting of metal ions linked together by biomolecules as organic bridging ligands, and are emerging as a new interdiscipline based on molecular coordination chemistry and biornaterials science. Nucleobases, the key constituents of nucleic acids, have accessible nitrogen and oxygen electron lone pairs, which allows these molecules to act as muhidentate organic ligands. In this paper, a series of metal- biomolecule frameworks was successfully synthesized with different nucleobases via a solvothermal system. These MBioFs exhibit brilliant micro-structures which are distinct with each other and dependent on the nucleobase linkers consisting in the frameworks for their different coordination properties. In addition, they are able to adsorb and release organic molecules repeatedly, and can be regarded as the sorbent to treat waste water.
