A dye, having a structure represented by formula (1A):
wherein A represents a group of atoms necessary for forming a ring together with the carbon-nitrogen bond; at least one of Y
1A
and Y
2A
represents an acidic group, in which when they each represent an acidic group, they may be the same as or different from each other, or when only one of them represents an acidic group, the other represents an electron-withdrawing group; D represents a group to give a dye; n represents an integer of 1 or greater; L represents a single bond or a divalent linking group; and Y
3A
represents an acidic group.
An organic dye used in a dye-sensitized solar cell is described, having general formula (1):
D-Sp1-Ch-Sp2-Acc-Y (1)
wherein the groups D, Ch, Acc and Y are conjugate with each other, the group D is a donor group, the group Ch is a chromophore rendering low HOMO-LUMO gap or a polyaromatic chromophore, the group Acc is an acceptor group, the group Y is an anchoring group, and each of Sp1 and Sp2 represents a single bond or a spacer group allowing conjugation between the groups D and Ch or between the groups Ch and Acc.

The invention discloses a compound having branching alkyl chains, the method for preparing the same and use thereof in photoelectric devices. By applying the branching alkyl chains as the solubilizing group to the preparation of organic conjugated molecules (for example, organic conjugated polymers), the number of methylenes between the resultant alky side chains and the backbone, i.e., m>1, which can effectively reduce the effect of the alkyl chains on the backbone π-π stacking, thereby ensuring the solubility of the organic conjugated molecule while greatly increasing the mobility of their carriers. It is suitable for an organic semiconductor material in photoelectric devices such as organic solar cells, organic light emitting diodes and organic field effect transistors, etc.
