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 facile and efficient microwave-assisted reaction of 1,8-naphthalicanhydride derivatives with primary amines, leading to the synthesis of 1,8-naphthalimides, has been developed. Subsequently, the free radical scavenging properties of the 1,8-naphthalimide derivatives were evaluated against 2,2-diphenyl-1-picrylhydrazyl (DPPH•). The results showed that the scavenging activities of compounds 2a, NBNA
