Molecular assembly is the self-arrangement of molecules or molecular groups under a limited condition, which is an important area in supramolecular chemistry. By employing intermolecular interactions, molecular assembly method can be applied in various areas in matter science research, leading to a very active multidisciplinary area. The research that how simple molecules to form hierarchical ordered aggregation structures through non-covalent interactions can not only provide a new way to explore new assemblies, but also paving an efficient route to design new materials. We use molecules or molecular complex as the fundamental building blocks and our main research focus on exploring the interactions and synergistic effect of different molecular building blocks. Our final purpose is to construct novel assembling structures and develop supramolecular materials with potential applications, based on the rational combination of molecules and aiming at different scientific questions.

The research and development of organic functional materials is of great importance and as a new growing point in the field of advanced materials. In recent years, organic functional materials have made remarkable progress and breakthrough in organic light-emitting diodes, solar cells, sensor and other relative optoelectronic area. For example, organic photoconductive materials have been widely used in reprography and laser printers. OLED/PLED display technology has been applied in the small display area such as cell phone, personal data processor and car dashboard. And large display screen technology (colored TV) has also gradually become mature and met the requirements for markets. For sustainable developments in organic functional material research and their applications in the device fields, it is of great significance to explore the pathway of improving the material performance and developing new material system by effective combination of theory and experiment.

Organic optoelectronic materials (organic materials, coordinated materials and polymeric materials) have attracted wide applications in various electronic devices. The major challenge in designing organic optoelectronic materials with high quantum yield, good charge mobility and strong absorbance relies on not only molecular structure but also supramolecular packing modes. This research group focuses on the construction of high-performance organic functional materials as well as their applications in organic light emitting diodes, organic solar cells and organic semiconductors. In addition, the practical application and the key technology of organic optoelectronics are also important issues we are concerned.

Structure is the basis of function. Supramolecular structures are built above the interaction between molecules. Methods and techniques for studies on the structure of assemblies and the assembled process are most required. So, the perspective of Department of Supramolecular Spectroscopy and Theoretics is to build, develop, modify and employ the theories and methods to answer questions in supramolecular science. Main research interests involve: (1) Exploring new theoretical, spectroscopic and experimental methods for supramolecular systems. We developed many high-sensitive techniques, e.g. surface-enhanced Raman scattering spectroscopy (SERS), to investigate the physical chemical subjects about surface and interface and the mechanism of SERS on metals or semiconductors.
