A number of novel N ‐substituted‐1,8‐naphthalimides have been prepared and their fluorescence yields measured in water at p H 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).
