Abstract：
A 4-amino-1,8-naphthalimide containing tetramethylpiperidine in N-position was synthesized. The prepared 1,8-naphthalimide was found to possess bright yellow-green fluorescence in a solid state, which could be switched-off in the presence of acid vapors and then switched-on after exposure on base vapors. The observed fluorescence quenching or enhancement, respectively, was more than 10-fold. This behavior was quite opposite to that of the similar 4-oxy-1,8-naphthalimide, in which a well-pronounced PET process operates. In addition, the observed fluorescence quenching was accompanied with color change from yellow to red. Based on these results, the reported 4-amino-1,8-naphthalimide was successfully applied as a reversible solid-state emissive chemosensing material for rapid detection of acid-base vapors for multiple usage.
摘要：
合成了在N位含有四甲基哌啶的4-氨基-1,8-萘酰亚胺。发现制备的1,8-萘酰亚胺在固态下具有明亮的黄绿色荧光，可以在酸蒸气存在下关闭，然后在暴露于碱蒸气后打开。观察到的荧光猝灭或增强，分别,超过10倍。这种行为与类似的4-氧-1,8-萘酰亚胺的行为完全相反，其中一个很明显的PET工艺操作。此外,观察到的荧光猝灭伴随着从黄色到红色的颜色变化。基于这些结果,报道的4-氨基-1,8-萘酰亚胺已成功用作可逆固态发射化学传感材料，可快速检测多种用途的酸碱蒸气。
