Dr. Shon’s research focuses on two general areas: organic-metal nanoparticle composite materials and self-assembly of nanomaterials.

Dr. Young-Seok Shon is an organic chemistry professor at the Department of Chemistry & Biochemistry in California State University Long Beach. He is joining the department as an associate professor. Prior to this position, he served for 5 years as an assistant professor at Western Kentucky University, where he taught Organic Chemistry, Advanced Organic Chemistry, Polymer Chemistry, and General Chemistry. He also earned a reputation as a nanomaterial researcher who studied the synthesis and characterization of various monolayer-protected nanoparticles and nanostructured films.

His research seeks to find an improved method to control the composition of nanoparticles (organic surfaces, core metals, and core sizes) and build new nanoparticle assemblies with interesting properties and applications. His research group studied the facile synthesis of new C60-conjugated gold nanoparticles and C60 (or C70)-nanoparticle hybrid films. Chemical, thermal, and ultrasonic stability of hybrid nanoparticles and nanoparticle-multilayer films were also investigated. Nanoparticle-cored dendrimers (NCDs) and nanoparticle megamers were synthesized from monolayer-protected gold nanoparticles using either single- (convergent approach) or multi-step reactions (divergent approach). His research group also performed systematic studies on the synthesis of functionalized monolayer-protected clusters (MPCs) from mixtures of alkanethiols and one-pot synthesis of monolayer-protected Ag nanoparticles from sodium S-dodecylthiosulfate (Bunte Salt) in aqueous solution. The various synthetic methods of monolayer-protected Au, Ag, Cu, Pt, and Pd nanoparticles and organic reactions of monolayer-protected nanoparticles were investigated. In addition, electronic structure of ensembles and sulfur surface-enrichment of monolayer-protected gold nanoparticles were explored. His current work at California State University, Long Beach includes the synthesis and application of ionic monolayer-protected clusters (IMPCs) and electroactive/photoresponsive nanoparticle-cored dendrimers.

Education

He received a bachelor’s degree and master’s degree in Chemistry from Sogang University in Seoul in 1991 and 1993. Dr. Shon received Ph. D. degree from the University of Houston in 1999.
