TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Components: (I) are phenyl-pyren-1-yl-amine compounds of formulae (II)-(XI). Preferred Definitions:    Z = substituent of thiophene, vinyl, polyvinyl, benzene, naphthalene, anthracene, fluorene, biphenyl, pyran, pyrrole and/or carbazole; and    A = substituent of COOH, phosphorous acid, sulfonic acid, phosphinic acid, hydroxy acid and/or oxycarboxylic acid.    SPECIFIC COMPOUNDS - 3 Compounds (I) are disclosed i.e. (Z)-3-(4-((E)-2-(4-((4-tert-butyl-phenyl)-pyren-2-yl-amino)-phenyl)-vinyl)-phenyl)-2-cyano-acrylic acid of formula (Ia), (Z)-2-cyano-3-(4-((E)-2-(4-(phenyl-pyren-2-yl-amino)-phenyl)-vinyl)-phenyl)-acrylic acid and (Z)-3-(4-((E)-2-(4-((4-butyl-phenyl)-pyren-2-yl-amino)-phenyl)-vinyl)-phenyl)-2-cyano-acrylic acid.    EXAMPLE - Aniline (127.5 mmol), 2-bromopyrene (102 mmol), tris(dibenzylidene acetone)dipalladium (1.53 mmol), (2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (3.06 mmol) and sodium-tert-butoxide (132.6 mmol) were melted in toluene (100 ml) and mixed for 24 hours. Then the reaction mixture was worked up to give N-phenylpyrene-2-amine (A) liquid was obtained. (A) (22.8 mmol), 4-bromobenzaldehyde (29.64 mmol), tris(dibenzylidene acetone)dipalladium (0.342 mmol), tris-tert-butyl phosphine (0.684 mmol) and sodium-tert-butoxide (29.64 mmol) were melted in toluene (100 ml) and they were mixed for 24 hours. The reaction mixture was worked up to give 4-(N-phenyl-N-(pyrene-7-one)amino)benzaldehyde (B) liquid. Sodium-tert-butoxide (19 mmol) was melted in anhydrous tetrahydrofuran (100 ml), and then methyl triphenyl phosphonium bromide (17.8 mmol) was slowly added. Then (B) was melted in anhydrous tetrahydrofuran (30 ml) and added to the solution for 12 hours. The reaction mixture was worked up to give N-phenyl-N-(4-vinylphenyl)pyrene-2-amine (C). (C) (100 ml), 4-bromobenzaldehyde (17.4 mmol), 2,6-di-tert-butylcresol (0.87 m mol), sodium-tert-butoxide (9.57 mmol) and trans-di( mu -acetato)bis((di-o-tolylphosphino)benzyl)-dipalladium (II) were added and melted in N,N-dimethylacetamide (50 ml) and then they were mixed for 24 hours at 80 degrees C. The reaction mixture was worked up to give N-phenyl-N-pyrene-7-one-4-(4-aminostyryl)benzaldehyde (D). (D) (4.2 mmol), 2-cyanoacetic acid (6.3 mmol), and piperidine (10.5 mmol) were added into the flask and melted in acetonitrile (50 ml) and reflowed for 12 hours. The reaction mixture was worked up to give N-phenyl-N-pyrene-7- one-4-((4-aminostyryl)-2-cyano)-3-phenyl acrylic acid.
