合成并表征了两组新的萘-1,8-二羧酸衍生化合物,即6-氨基-1,8-萘酐衍生物和2-羟基-6-氨基-1,8-萘二甲酰亚胺衍生物。研究了所有合成化合物的光谱性质,以便用于生物成像研究领域,并用作制备新型荧光生物活性化合物的中间体。从非极性溶剂到极性溶剂均观察到正溶剂溶变色,并使用加泰罗尼亚语多元线性回归分析对其进行了讨论。进行了萘酐和1,8-萘二甲酰亚胺衍生物的光物理特性的比较研究。新型萘酐6-(4-苄基-哌嗪-1-基)苯并[ de ]异戊烯-1,3-二酮(3)代表了极性较低的溶剂中荧光量子产率的最高值。结果表明,萘酐衍生物的量子产率高于萘二甲酰亚胺衍生物。
Novel naphthalimide fluorescentorganicnanoparticles with aggregation-induced emission enhancement properties were designed and synthesized, which were used as a highly selective and sensitive “turn-on” fluorescent probe for Fe3+ detection in water. Fluorescence imaging experiments of Fe3+ ions in living cells demonstrated the value of this probe for practical applications in biological systems.
Environmental pH plays an irreplaceable role in both cellular processes and production, and anomalous pH changes within cells may lead to various diseases. To tackle this issue, we designed and synthesized the novellow-cytotoxicityfluorescentprobe called . The probe incorporates 1,8-naphthalimide as the fluorescence emitter, 1-methylpiperazine as the pH-sensitive moiety, and utilizes 3-aminopropyltriethoxysilane
