| Outline of Final Research Achievements |
We synthesized a group of diradical metal complexes and studied their functions, in order to obtain design strategy of novel multi-signaling cation sensors. The diradical metal complex having the ligands linked by a propylene group was synthesized to ensure the high kinetic stability which was required to be used as a sensor in solution. The half-life indicating its kinetic stability was measured for the diradical complexes with and without the linker. The half-life of the diradical complex with the linker is 1000 times longer than that without the linker. Additionally, we found the near-infrared absorption switching of the diradical complex caused by the inclusion to cyclodextrin.
