摘要

A dye including an anchoring group in its molecular structure, said anchoring group allowing a covalent coupling of said dye to a surface, for example a surface of a nanoporous semiconductor layer, said anchoring group being represented by formula 1 wherein attachment of said anchoring group within said molecular structure of said dye is at the terminal carbon marked with an asterisk in above formula, wherein G is selected from -COOH, -SO3H, -PO3H2, -BO2H2, -SH, -OH, -NH2, preferably -COOH, wherein A is selected from the group comprising H, -CN, -NO2, -COOR, -COSR, -COR, -CSR, -NCS, -CF3, -CONR2-OCF3, C6H5-mFm, wherein m=1-5, R being H or any straight or branched alkyl chain of general formula -CnH2n+I, n=O-12, preferably 0-4, or any substituted or non-substituted phenyl or biphenyl.
