DYE CONTAINING BINDING GROUP IN MOLECULAR STRUCTURE Russian patent published in 2013 - IPC H01G9/20 H01L51/00 C07F15/00 C07D209/04 C07D401/02 C09B57/10 H01L31/04 C07D209/12 C07D409/14 C07C49/533 

FIELD: chemistry.

SUBSTANCE: invention relates to a dye which contains a binding group in its molecular structure, wherein said binding group provides covalent bonding of said dye to a surface, and said binding group is represented by formula 1 , in which the binding site of said binding group inside said molecular structure of said dye is located at the terminal carbon atom marked with an asterisk in said formula. G is selected from -COOH, -SO₃H, -PO₃H₂, -BO₂H₂ -SH, -OH, -NH₂, A is selected from a group consisting of H, -CN, -NO₂, -COOR, -COSR, -COR, -CSR, -NCS, -CF₃, -CONR₂, -OCF₃, C₆H₅._mF_m, in which m=1-5, R is H or any linear or branched alkyl chain of general formula -C_nH_2n+1 n=0-12, preferably 0-4, or any substituted or unsubstituted phenyl or biphenyl, where said dye is represented by formula (2) or formula (4), where said chromophore is a squarylium dye derivative or a croconium dye derivative, which is capable of absorbing light with a wavelength in the visible and/or infrared range, preferably in the range from 300 to 1200 nm or part thereof, wherein each derivative of said squarylium dye and said croconium dye has aromatic ring systems Ar₁ and Ar₂, that are bonded to the squarylium dye or croconium dye derivatives. The invention also relates to methods of producing chromophore which is part of a dye and is a dye itself, as well as devices using said dye and applications thereof as a sensitising agent and a sensor.

EFFECT: disclosed dyes are also capable of absorbing light in the long-wave spectral range.
