The mission of SKLSSM is to conduct fundamental research in supramolecular chemistry, which refers to the chemistry beyond that of molecules and focuses on systems comprised of a discrete number of assembled molecular components brought together by intermolecular interactions. Supramolecular systems feature intelligent molecular designs leading to programmed self-assembly, dynamic reversibility and structural diversity. In agreement with the academic committee, our research goals are anchored on developing the following interdisciplinary keystones: (1) Supramolecular assemblies and their dynamics; (2) Supramolecular photo/electro-functional materials; (3) Biosupramolecular assemblies and (4) Spectroscopic studies and simulations of supramolecular assemblies. To date, SLKSSM has achieved significant advancements in the field of supramolecular chemistry, and has won 3 National Natural Science 2nd level awards, and the honorary title of Innovative Research Team by the National Natural Science Foundation of China.
The research currently concentrates on the biomimetic supramolecular assemblies and their functions. The scientific activities carried on by several labs include as follows: 1) Designing a series of highly efficient supramolecular enzyme mimics with complex and hierarchical structures on the basis of molecular recognition in order to reveal the catalytic mystery of natural enzymes; 2) Using the multiple non-covalent interactions to construct the biosupramolecular assemblies with multi-level and multi-demensional architectures and to realize the integration of multiple functions of the biosupramolecular assemblies as well; 3) Taking various analytic techniques like single molecular force spectroscopy to understand the dynamic principle of supramolecular interactions of the biological systems.
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.
In view of complex supramolecular systems, the research works mainly focus on the following parts: preparation of the microstructures and functional building blocks in different scale; establishment of various methods to achieve supramolecular architectures; construction of multiple and multiscale structures in nano- and micro-scale; control of structural ordering by optimizing the parameter and process of self-assembly; exploration of the structure related photoelectric, photonic and biological functionalities and intelligences; and investigation of the relationship between the structures and functionalities.
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 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. (2) To design, develop and modify spectroscopic methods and instruments for learning the interaction between molecules. For example, SPR-SERS co-detection and many new SERS approaches for protein analysis and detection, etc. (3) Utilizing spectroscopic techniques and theories to study the structural basis of protein function and dysfunction, including structures of membrane proteins and self-assemblies of amyloid peptides. (4) To build and develop theoretical models, calculation methods and simulation engines for the studies on the synergy effect dominated formation processes, properties and functions in supramolecular systems.
