Outline of Final Research Achievements

The purpose of this study was to verify the mechanism of unknown chemical reactions that occur on the surface of silver nanoparticles. The research results obtained are: (1) When 4-aminobenzenethiol (4-ABT) molecules are attached to the surface of silver nanoparticles and irradiated with visible laser light, they are usually azoized and surface-enhanced Raman scattering (SERS) spectrum of its dimers is observed. However, when the 4-ABT concentration is 10^-8 M or lower, a new spectrum previously unreported was observed. (2) We reproduced this new SERS spectrum by quantum chemical calculation method. this new spectrum was not the result of the chemical reaction but the SERS spectrum of a single 4-ABT molecule, and various peaks appeared depending on the molecular fluctuation.

Academic Significance and Societal Importance of the Research Achievements

4-アミノベンゼンチオール(4-ABT)分子は表面増強ラマン散乱(SERS)研究の分野で既に20年以上研究されてきた重要な分子のひとつである。今回、そのような長い研究の歴史を持つ分子にも拘わらず新たなSERSスペクトルが発見されたため、それ自体に大きな意義がある。またそのSERSスペクトルの由来を計算化学で調べたところ、何かの化学反応の結果ではなく4-ABT分子そのものが由来と推測される結果が得られた。しかも通常、ラマンスペクトルとSERSスペクトルは同一であるが、4-ABT分子では両者が異なっておりこれも新たな発見である。これまでの20年の研究の歴史に新たな風を吹き込むもので非常に意義深い。
