Synthesis and fluorescence properties of naphthalimide-containing Tröger’s bases
摘要:
Troger's bases based on the naphthalimide fluorophore have been prepared from N-alkyl-4-amino-1,8-naphthalimides. The fluorescence emission intensity of these dyes is highly medium dependent. In cyclohexane, these dyes emit near 440 nm with high quantum yields, addition of cosolvents reduces the fluorescence intensity near 440 mn and leads to increased fluorescence intensity around 480 nm.
