| Outline of Final Research Achievements |
The aim of this study is to develop novel quantum magnetic states on various spin lattices realized by organic radicals, which form ideally isotropic spin system. Rational designing toward various spin lattices has been developed by tuning the π-conjugation on organic radical molecules. High-dimensional spin lattices have been realized by polyradicals and/or tuning the dihedral angle between π-conjugated planes. Series compounds have been synthesized where both of the sign and the magnitude of the magnetic interactions have been tuned. Their physical properties in magnetic fields at low temperature have been examined. The properties of spin-liquid state have been elucidated, and the quantum effect even in three-dimensional magnetic ordered state have been successfully observed.
