The development of fluorescent heterocyclic compounds bearing s-triazine and cyclotriphosphazene scaffolds for researching the structure–property relationship and high-efficiency amine sensing is still challenging. Herein, we prepared two polypodal aldehyde-based flexible organic compounds based on triazine and cyclotriphosphazene units (TRIPOD and HAPCP). Moreover, two hydrogen-bonded organic frameworks, namely HOF-TRIPOD and HOF-HAPCP, with different photophysical properties and structural packing modes were obtained. In addition, the fluorescence response of the two molecules to aliphatic amine was studied, in which they all showed good selectivity and an obvious fluorescence enhancement effect to ethylenediamine. The utilization of these fluorescent molecules as a sensor platform material could be applied for ethylenediamine detection.

带有 s-三嗪和环三磷腈支架的杂环化合物：简便合成、氢键有机框架结构和荧光胺传感

含荧光杂环化合物的研制用于研究结构-性质关系和高效胺传感的-三嗪和环三磷腈支架仍然具有挑战性。在此，我们制备了两种基于三嗪和环三磷腈单元的多足醛基柔性有机化合物（TRIPOD 和 HAPCP）。此外，还获得了两种具有不同光物理性质和结构堆积方式的氢键有机骨架，即HOF-TRIPOD和HOF-HAPCP。此外，研究了这两种分子对脂肪胺的荧光响应，均表现出良好的选择性，对乙二胺有明显的荧光增强作用。这些荧光分子作为传感器平台材料的利用可用于乙二胺检测。
