New bis(2, 2'-bithienyl)methane derivative and method of producing thereof, molecularly imprinted polymer film, method of producing therof and its use

摘要

(I) A bis (2,2-bithienyl)methane derivative of formula (I) (bis(2,2-bithienyl)-(4-amino-phenyl)methane). A method of producing the bis (2,2-bithienyl)methane derivative of formula (I) is provided wherein the initial solution of 2,2-biothiophene and 4-acetaminobenaldehyde in ethylene glycol is reacted with perchloric acid at a temperature ranging from 40 to 90oC, which results in bis(2,2-bithienyl)-(4-aminophenyl)methane of formula 1. A method for fabricating a molecularly imprinted polymer and a molecularly imprinted polymer film produced by that method consisting of a polymer molecularly imprinted with nitroaromatic compounds, in particular those selected from the group comprising 2,4,6-trinitrophenol (TNP), 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), and 2,4-dinitrotoluene (DNT) are also outlined. The molecularly imprinted polymer film is useful as a chemical sensor for the selective detection and determination of nitroaromatic compounds.
