Research Abstract

The research project targeted creating novel high-order functions by strategic integration of the functional molecular units (FMUs) in the coordination frameworks. A porous coordination polymer {Fe(pz)[Pt(CN)4]} (pz = pyrazine) was used as a key material. The compound are rationally incorporated different FMUs, Fe(II) as a spin crossover center, p-conjugated ligand pz and coordination unsaturated Pt(II), in the porous framework to interlock the physical properties of FMUs and structural function of the framework. In the project, we succeeded in the following points for creating new multifunctional compounds, (1) control of the spin state through host-guest interaction and elucidation of its mechanism, (2) enhancement of guest responsivity by meso-particulation and (3) preparation of liposome-metal complex composite.
