| Research Abstract |
As a novel supramolecular approach to rationalized construction of organic molecule-based magnets, we have proposed "bio-inspired molecule-based approach", in which the complementary hydrogen bonding between nucleobases are introduced to stable radical molecules with various spin quantum numbers for the control of the molecular arrangement. We have succeeded in synthesizing the first example of a Watson-Crick type cytosine-guanine hydrogen-bonded complex composed of cytosine- and guanine-substituted nitroxide radical molecules, which have been characterized by single-crystal X-ray crystallography. As another approach to construct a molecular spin assembly, we have proposed and designed molecular spin assembly templated by single-stranded oligonucleotides. A minimal model system for the assembly containing a covalent base vacancy has been designed, in which nucleobase-substituted radicals should be confined in the base-specific manner.
