Major research interest and accomplishments
- Organic molecule-based magnets, Radical and carbene chemistry, Correlated internal rotation, Organic reactions in sub- and supercritical water.
- *In 1984 he prepared hydrocarbon tri-carbene and tetra-carbene to demonstrate that their 2p-electron spins aligned in parallel and paramagnetic moments became greater than those of iron and Gd salts due to five 3d- and seven 4f-electron spins, respectively. The highest spin nona-carbene ever prepared had a S = 9 ground state. Aminoxyl radicals and pyridylcarbenes were assembled into polymers by coordination with magnetic metal ions to give mixed metal-organic molecule-based magnets. They included a ferromagnet with the Curie temperature of 46 K and photomagnets where only the irradiated part become strongly magnetic.
- *Earlier he designed and prepared a whole series of di-X as molecular cog-wheels and demonstrated that they undergo almost free correlated internal rotation by various physical and chemical measurements. Since the rapid internal rotation of the cog-wheels does not get off the track, the di-9-triptycyl compounds carrying different benzene ring gave isolable stereoisomers due to the phase of the label in spite of the rapid internal rotation.
- *More recently he developed a number of preparative organic reactions that proceed by way of aldol condensation and Michael addition in sub- or supercritical water in the absence of any added catalysts.
