摘要： The invention describes new 3,3-dimethyl-2-styryl-3H-indole derivatives and their synthesis method using a flow reactor. The compounds of the invention are obtained in 61-98% yield by condensation of the corresponding 3H-indole chlorides with corresponding benzaldehydes for 1 hour in ethylene glycol at 125 °C. The stream is then cooled and passed through a column filled with a sorbent that binds the unreacted aldehyde. After evaporation of the solvent, it is returned to the preparation of the initial solutions, and the residue is purified by chromatography. New derivatives of 3,3-dimethyl-2-styryl-3H-indole can be used as pH sensors or intermediates for the synthesis of other special dyes (pH sensors of biological media, cell markers, etc.).

摘要： The invention relates to novel fluorescent whitening agents, compositions or mixtures thereof with known fluorescent whitening agents, their preparation, and their use. The novel fluorescent whitening agents contain three structural subunits derived from 4,4'-diamino-2,2'-stilbenedisulfonic acid. The novel compounds and their mixtures with known FWAs show very good effectiveness as fluorescent whitening agents for cellulosic materials, in particular for paper.

摘要： The present invention provides dyes, reactive dyes and labeled reagents that may be used in the detection or quantification of desirable target molecules, such as protein, nucleic acids and cellular organelles, Dyes are provided that may be used free in solution where the binding of the dye to the target molecule provides signal generation. Dyes are also provided that comprise reactive groups that may be used to attach the dyes to probes that will bind to desirable target molecules. The novel dyes of the present invention have been modified to provide beneficial properties.
