This book collects all the latest advances in the leading research of the circularly polarized luminescence (CPL) of small organic molecules. Compared with that of lanthanide-based fluorophores, the research into the CPL of small organic molecules is still at the developmental stage for their relatively smaller dissymmetric factors, but has been a source of widespread attention recently. The book includes the state of the art of the discoveries in CPL organic molecules, such as helicenes, biaryls, cyclophanes, boron dipyrromethene dyes, and other chiral molecules, mostly in their isolated states, covering all possible chiral substances for future applications. This book also highlights the recent development of CPL instruments as well as time-resolved circular dichroism spectroscopy, to facilitate the further development and future design of CPL molecules.

Tadashi Mori obtained his PhD in 1997 from Kyoto University and moved to Osaka University from 1998, where he is now Associate Professor. During these periods, he also worked as a postdoctoral and a JSPS research fellow in Houston University (Prof. Jay K. Kochi), a visiting professor in Georgetown University (Prof. Richard G. Weiss), an Alexander von Humboldt Fellow in Universität Müster (Prof. Stefan Grimme), and a Fostering Joint International Research Fellow in Technische Universität München (Prof. Thorsten Bach). His main research interests include the chiroptical properties of ground- and excited-state molecules, (supra) molecular complexes, and their photochemistry.
