Abstract:

The preparation of organic functional materials has become one of the most important research areas in modern organic chemistry and allows the industrial manufacture of relative intermediates and products. At present, a basic organic experimental course mainly includes study of unit operations and synthesis of simple fine chemicals; extension of teaching content and promotion of engagement between education and emerging industries offer considerable strengthening the knowledge system. To this end, this project selected one of the research frontiers in organic chemistry–development of organic thermally activated delayed fluorescence (TADF) materials. This project can simultaneously supplement the existing types of organic reactions and guide students in understanding the key role of synthetic reactions in constructing organic functional materials. Furthermore, in addition to the elucidation of modern fluorescence spectroscopy technology, this project can reveal the scientific connection between organic molecular structures and the properties of organic functional materials to complete the systematic teaching of the "synthesis–molecular structure–photoelectric properties" knowledge chain. Through material preparation, structure determination, and TADF property measurement, students can not only strengthen their basic knowledge of experimental operations but also understand nuclear magnetic resonance spectrometry and fluorescence spectroscopy techniques. This experiment enriches the course of undergraduate organic experiments and allows students to experience the complete scientific research process, thus facilitating the formation of a gradient, multi-disciplinary knowledge system.
