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 —CnH2
n
+I, n=O-12, preferably 0-4, or any substituted or non-substituted phenyl or biphenyl.
一种染料,其分子结构中包括一个锚定基团,该锚定基团允许将该染料共价耦合到表面,例如纳米多孔半导体层的表面。该锚定基团由公式1表示,其中上述公式中带星号的末端碳上的锚定基团连接在该染料的分子结构内。其中G从—COOH,—SO3H,—PO3H2,—BO2H2,—SH,—OH,—NH2中选择,优选为—COOH。其中A从H,—CN,—NO2,—COOR,—COSR,—COR,—CSR,—NCS,—CF3,—CONR2-OCF3,C6H5-mFm中选择,其中m=1-5,R为H或一般式—CnH2n+I的任何直链或支链烷基链,n=0-12,优选为0-4,或任何取代或未取代的苯基或联苯基。
