The present invention discloses an isodiketopyrrolopyrrole dye and use thereof. A series of pure organic dye based on isodiketopyrrolopyrrole are synthesized in the present invention, using 4,4-dihexyloxytriphenylamine as an electron donor, isodiketopyrrolopyrrole as a -bridge, and cyanoacetic acid as an electron acceptor and an anchoring group, and with a alkyl chain introduced on an isodiketopyrrolopyrrole group. The types of dyes have a relatively good light-harvesting performance as well as a relatively large steric hindrance, and they are not easy to gather while being absorbed on a semiconducting film. The pure organic dye with isodiketopyrrolopyrrole as an electronic -bridge, which is used in a dye-sensitized solar cell, has a good ability of inhibiting the recombination of electrons, and the dye-sensitized solar cells have a high photoelectric conversion efficiency.

The present invention provides compounds of formula (1) and an electronic device comprising the compounds as semiconducting material.
