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, -SOH, -POH, -BOH-SH, -OH, -NH, A is selected from a group consisting of H, -CN, -NO, -COOR, -COSR, -COR, -CSR, -NCS, -CF, -CONR, -OCF, CH.F, in which m=1-5, R is H or any linear or branched alkyl chain of general formula -CHn=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 Arand Ar, 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.32 cl, 23 ex, 20 dwg |
