    • A class of predominantly hydrophilic 1,8-naphthalimide dyes. The dye contains at least two 1,8-naphthalimide ring systems, joined by a spacer moiety. Each of the 1,8-naphthalimide ring system has a ring nitrogen atom and bears, at the 4 position, an amino nitrogen atom, carrying a hydrogen. The remaining unsatisfied valences, if present, of the ring nitrogen atoms or the amino nitrogen atoms, or all, are occupied by one or more alkyl substituents. Each of the 1,8-naphthalimide ring system is free of an azo substituent and is also free of a nucleofuge. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species can cause structural changes in lipid and any associated proteins and polypeptides, extra- or intra-cellular or transmembrane, leading to polymerization and crosslinking.
    • 一类主要亲水的1,8-萘二甲酰亚胺染料。 该染料含有至少两个由间隔部分连接的1,8-萘二甲酰亚胺环体系。 每个1,8-萘二甲酰亚胺环系具有环氮原子,并且在4位具有携带氢的氨基氮原子。 环状氮原子或氨基氮原子或全部的剩余不饱和化合价如果存在,则被一个或多个烷基取代基占据。 每个1,8-萘二甲酰亚胺环系均不含偶氮取代基,也不含核离子。 在独立于氧的存在或不存在的环境中通过活化剂活化时,这些化合物产生活化物质。 活化的物质可以引起脂质和任何相关的蛋白质和多肽,细胞外或细胞内或跨膜的结构变化,导致聚合和交联。

    • A method for the qualitative or quantitative determination of the deleterious agent in a substantially non-aqueous medium, such as an oil. The method involves using a non-azo 1,8-naphthalimide dye for the detection or quantitation of the total hydrogen ion activity in a substantially non-aqueous medium. The method includes the steps of: Mixing the dye with the substantially non-aqueous medium, which may or may not contain any hydrogen ion, to form a mixture; irradiating the mixture with a fluorescent light sufficient to cause the mixture to emit a detectable fluorescent emission spectrum; detecting the fluorescent emission spectrum of the mixture; and comparing the detected fluorescent emission spectrum with standard fluorescent emission spectra generated by reacting the dye with different known hydrogen ion activities, wherein differences between the fluorescent emission spectra compared are dependent upon the presence or levels of the hydrogen ion activity present in the mixture.
    • 用于在基本上非水介质如油中定性或定量测定有害剂的方法。 该方法包括使用非偶氮1,8-萘二甲酰亚胺染料来检测或定量在基本上非水介质中的总氢离子活度。 该方法包括以下步骤:将染料与基本上非水介质混合,其可以含有或不含有任何氢离子以形成混合物; 用足以使混合物发射可检测的荧光发射光谱的荧光照射混合物; 检测混合物的荧光发射光谱; 并且将检测到的荧光发射光谱与通过使染料与不同的已知氢离子活性反应产生的标准荧光发射光谱进行比较,其中所比较的荧光发射光谱之间的差异取决于混合物中存在的氢离子活性的存在或水平。
