METHOD OF SYNTHESISING 2-DODECYL-5-(2,3,7,8-BIS-(9H, 10H-ANTHRACENE-9,10-DIYL)PYREN-1-YL)THIOPHENE - MONOMOLECULAR OPTIC SENSOR FOR DETECTION OF NITROAROMATIC COMPOUNDS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of obtaining 2-dodecyl-5-(2,3,7,8-bis-(9H, 10H-anthracene-9,10-diyl)pyren-1-yl)thiophene, which consists in the interaction of 1-bromopyrene with 2-dodecyl-5-tributylstannylthiophene by the Stille reaction with obtaining the first half-product 5-(pyren-1-yl)-2-dodecylthiophene, with the following bromination of the latter with obtaining the second half-product 2-dodecyl-5-(3,6,8-tribromopyren-1-yl)thiophene, its following heating with anthracene and sodium amine in the argon atmosphere.;EFFECT: developed is the novel method of synthesising a derivative of pentasubstituted pyrene with the application of a cross-combination by Stille and highly reactive arine intermediates, which in a result leads to the synthetic availability of pentasubstituted pyrene derivatives, which can be applied for distant detection of nitroaromatic compounds present on surfaces, in solutions of nonpolar solvents, water and in air.;2 dwg, 1 tbl
