In this experiment, the electron-deficient boron and the electron-donating nitrogen were used as the starting points of the rational design. Furthermore, organic carriers of B and N were selected based on the principle of aggregation-induced emission (AIE). An environmentally friendly, economic and convenient "one-pot" synthesis method was employed to obtain crystal compounds, and the structures of these compounds were characterized. The optical properties of compounds, including "presence or absence", "color", and "strength", were regulated by changing ligands. Students will understand the idea that the structure determines properties and will experience the visible and tangible chemical theories.

Key words: Lewis acid-base theory, Aggregation-induced emission, Tenon and mortise structure, Boron, Nitrogen
