Synthesis and fluorescent property of some novel bischromophore compounds containing pyrazoline and naphthalimide groups

A series of novel bischromophore compounds containing pyrazoline and naphthalimide were synthesized, and their structures were confirmed by means of IR, 1H NMR, UV and elementary analysis. The fluorescent spectrum showed that these compounds had good green fluorescence. The fluorescence emission wavelengths varied from 520 to 540 nm.
