The invention pertains to a method for preparing derivatives of the pyrazolinylnaphthalic acid having the general formula
1
where Ar
1
and Ar
2
are unsubstituted or substituted phenyl radicals bearing in the para position an alkylated or acylated oxy- or amino group, or a polynuclear aryl radical, and Ar
3
is a substituted N-naphthalimid or 1,8-naphthylene-1′,2′-benzimidazole. Compounds ofthe above general formula are high-efficient red organic luminophors and are used widely as luminescent components of dyes for plastics and liquid scintillators, in hydrogeology to study water streams, to label the chemical industry wastewaters, as laser dyes, etc.
本发明涉及一种制备吡唑基萘酸衍生物的方法,其具有以下通式1:
其中,Ar1和Ar2是未取代或取代的苯基基团,在对位位置带有烷基化或酰化的氧基或氨基,或是多核芳基基团;Ar3是取代的N-萘酰亚胺或1,8-萘亚咪唑基-1′,2′-苯并咪唑基。上述通式的化合物是高效的红色有机发光体,广泛应用于塑料染料和液体闪烁体的发光组分、水文地质学中用于研究水流、标记化工废水、激光染料等。
