Abstract:The area of molecular materials and devices mainly concerns the design and synthesis of conjugated organic molecules and polymers, investigations of the structures in the condensed states, studies of the relevant physical properties, and fabrication of devices. This very interdisciplinary area is one of the most important frontiers of modern sciences. This area develops very rapidly and many important breakthroughs have been realized in recent years. However, a number of issues still remain unclear. After many years of efforts, Chinese scientists have a very good position in this area.
