Particular attention will be focused on development of an effective one-pot self-assembly strategy involving paramagnetic metal centers for the preparation of magnetic metal-organic frameworks. Several self-assembly synthetic approaches for the synthesis of these coordination polymers and their structural and magnetic features in response to external stimuli such as temperature, guest-inclusion etc. will be studied. Structural characterization, magnetic properties and their applications will be examined. This proposal will be conducted in three years and include three main processes. Some specific targets are as follows: 1. The design of effective magnetic-transmitted organic ligands: several types of magnetic transmitted organic ligands such as multi-pyridine multi-phosphonate, and/or ?-diketone etc. will be designed. 2. The self-assembly of low-dimension MCPs: several synthetic strategies including transition metal directed self-assembly at room temperature or under hydrothermal conditions will be utilized in the preparation of these magnetic coordination polymers. The structural and magnetic properties of the resulting compounds will be characterized. 3. The changeable structural and magnetic behavior of MCPs: possible structure and magnetic behavior changes of as-synthesized MCPs upon tuning by external stimuli such as counterions, guest molecules, and temperature will be investigated. 4. Applications of the dynamic properties: the possible applications of tunable structural and responding magnetic behaviors in areas of magnetization controlled magnetic material will be examined.
