1) Theoretical Study and Design of Light-Driven Molecular Motors and Switches

Motors, as the engine of human social development, have pushed us into the industrial era. In the micro-world, the corresponding molecular motors, as the core of future nanodevices, are expected to bring about profound changes in human society again. The design and synthesis of molecular motors has always been a research hotspot in many disciplines, such as life, physics and chemistry. It is also one of the most challenging research fields.

Light-driven molecular rotation motors, represented by space-squeezed polyene synthesized by Feringa et al., have attracted special attention due to their superior energy input, unique operation mode and broad application prospects.

Understanding the photochemistry and photochemistry behind the light-driven molecule rotating motor, so as to optimize the performance of the motor, improve the energy conversion efficiency and design a new type of optical-driven motor, is the long-term goal of the research group.

2) Mechansims of Chemi- & Bio-luminescence

Bioluminescence is one of nature's masterpieces. Essentially, they are chemical reactions occur in organisms that convert chemical energy into light. The efficiency of energy conversion in this process is so high that most of the chemical energy is emitted in the form of fluorescence, but hardly exothermic. Therefore, bioluminescence is also called "cold light". Under the situation of exhaustion of non-renewable resources and unprecedented shortage of energy supply, it is undoubtedly of great practical significance to carry out research in this field.

At the same time, bioluminescence and chemiluminescence also have a unique position in theoretical chemistry: unlike the reaction (i.e., photochemistry) in which ordinary molecules are transited to the excited state by light excitation but eventually return to the ground state, in the process of chemiluminescence and bioluminescence, the transition from the ground state to the excited state is caused by the exothermic reaction of the molecule itself, which is called chemical excitation. How can this unusual transition be achieved without the excitation of external pumping light sources? Due to the limitations of theoretical models and methods, this mechanism has been plagued by theoretical and experimental chemists for many years.
