摘要:

以缺电子硼(B)以及可以给出电子对的氮(N)为设计出发点,基于聚集诱导发光(AIE)原理选择B与N的有机载体,采用环保、节约、方便的“一锅法”,合成化合物晶体,表征结构,通过配体的变化调节化合物光学性质“有无”“颜色”“强弱”变化,体会结构决定性质的思想,真正感受到“看得见,摸得着”的化学理论。

Abstract:

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.
