human health. However, the specific detection of FA remains a great challenge. Herein, we report a rational strategy for specific detection and imaging of FA through combining characteristic structure of a fluorophore merged with the modified ortho-phenylenediamine as a recognition moiety. After the reaction of FA and the propyl-modified ortho-phenylenediamine, the probe NP1 and NP2 based on naphthalimide
甲醛(FA)在许多生理过程中起着重要作用,并且与人类健康密切相关。然而,FA的特异性检测仍然是巨大的挑战。本文中,我们报告了通过结合与修饰的
邻苯二胺作为识别部分的荧光团的特征结构,对FA进行特异性检测和成像的合理策略。FA与丙基修饰的
邻苯二胺反应后,基于
萘二甲
酰亚胺荧光团的探针NP1和NP2表现出用于FA检测的开启荧光响应。尤其是探针NP2具有更大空间位阻的分子,对活细胞内源性FA成像具有优越的特异性。这项工作可以作为设计FA探针特定识别部分的一般策略。
