Synthesis and fluorescence ofN-substituted-1,8-naphthalimides
摘要:
AbstractA number of novel N‐substituted‐1,8‐naphthalimides have been prepared and their fluorescence yields measured in water at pH 7.4. The type of substitutent and the substitution pattern on the naphthalimide nucleus produce markedly different fluorescence yields, (quantum efficiencies, ø varying from ø = 0‐0037 for N‐(3‐N'‐morpholino‐1‐propyl)‐4‐amino‐3‐methoxy‐1,8‐naphthalirnide (7) to ø = 0–77 for N‐(3‐bromopropyl)‐4‐acetamido‐1,8‐naphthalimide (31).

A number of nitro- and dinitro-1,8-naphthalimides have been prepared as potential fluorescentprobes of hypoxiccells. The susceptibility of 4-nitro-1,8-naphthalic anhydrides and -naphthalimides to nucleophilic displacement of the nitro group has been demonstrated by reaction with 1-butanethiol to yield 4-butylthio derivatives. Attempted nitration of these 4-butylthio derivatives with sodium nitrate
