Three water- soluble fluorescent compounds with intense yellowish-green fluorescence were synthesized by the reactions of aniline-4-sulfonic acid, aniline-3-sulfonic acid and aniline-2,5-disulfonic acid with perylene-3,4,9,10-tetracarboxylic dianhydride respectively.

The relationship between the structure characteristics and the fluorescence of fluorescent compound was described.

The Fluorescent compounds of pyrazoline have been used in many field.

We introduced the history and development of zinc fluorophores,elvaluate their zinc sensitivity and predict their future perspectives.

he spectra of charge transfer complexes (CTC) of six fluorescent organic compounds, 1,4-bis (o-cyanostyryl) benzene, l- (o-cyanostyryl) -4-(o-chlorostyryl) benzene,1,4-bis (o-chlorostyryl) benzene, 1,2-bis (5-methylbenzoxazol-2-yl) ethylene , 2,5 -tris (5-ter-butylbenzoxazol-2-yl) thiophene, and 3-pheny-5,6-benzocoumarin with TCNE, DDQ,and TCNQ were determined spectrophotometrically.

Studies on synthesis and properties of pH sensitive fluorescent polymers;

Hyperbrunched polymer was synthesized from pentaerythritol(as the central core),1,2,4-trimellitic anhydride and epichlorohydrin,by using the peripheral carboxyls of the synthesized polymer molecules and ethylene glycol diglycidyl ether which have been changed the properties by 2-(4-carboxyl benzyl group-)benzoxazole reacting together,the hyperbrunchedr fluorescent polymer was formed.

Synthesis and application of fluorescent polymers are in the front line of the water treatment field.
