The organic fluorescent dyes are organic luminophores.Research on these dyes were rapidly developing in recent years.The categories of organic fluorescent,characteristics and application of them were discssed in the paper.c1Review of Regioselective Mononitration of Toluene$$$$ Sun Ling Shen Yongjia (Institute of Fine Chemicals,East China University of Science Technology, Shanghai 200237) Abstract p-Nitrotoluene becomes more and more important in the industry,while o-nitrotoluene is just in the opposite.However,the traditional nitration of toluene unavoidably forms majority of o-nitro to luene(ratio of p-isomer to o-isomer is ca.0.6).Therefore,it is necessary to study the progress of regioselective nitration of toluene.
