A series of 1,8-naphthalimide-based fluorophores containing different chromophores with varying conjugation and electron richness at the imidic nitrogen atom are synthesized and characterized. These amine-functionalized naphthalimides are bipolar in nature and exhibit interesting optical and morphological variations attributable to the nature of the N substituents. Despite the fact that the dyes are structurally different owing to variation of the substituent on the imidic nitrogen atom, their electronic characteristics are similar and originate from the 4-aminonaphthalimide segment. Nevertheless, they exhibit variations in morphology in the microscopic domain, and this is attributable to structural differences. Further, these fluorescent dyes display biocompatibility and are used in the bioimaging of cells.
合成并表征了一系列含有不同生色团的 1,8-萘酰亚胺基荧光团，这些生色团在亚氨基氮原子上具有不同的共轭和电子富度。这些胺官能化的萘酰亚胺具有双极性，表现出有趣的光学和形态变化，这归因于 N 取代基的性质。尽管由于亚氨基氮原子上取代基的变化，染料在结构上有所不同，但它们的电子特性相似，源于 4-氨基萘酰亚胺片段。然而，它们在微观领域表现出形态上的变化，这归因于结构上的差异。此外，这些荧光染料具有生物相容性，并用于细胞的生物成像。
