Patent ID: 7910226

Claim:
A semiconductor layer formation material, the semiconductor layer including at least a single layer, the semiconductor layer formation material comprising a semiconductor material for forming the single layer, porous particles each having a number of pores, and a dispersion medium, wherein the semiconductor material is in the semiconductor layer formation material in such that at least a part of the semiconductor material is filled in the pores of the porous particles, the semiconductor material is comprised of a compound having at least one polymerizable group, and the compound can be polymerized through its polymerizable groups and is represented by the following general formulas (A1) or (A2): wherein two R 1 s are the same or different and each independently represents a straight-chain alkyl group having 2 to 8 carbon atoms, four R 2 s are the same or different and each independently represents a hydrogen atom, a methyl group or an ethyl group, Y represents a group containing at least one substituted or unsubstituted aromatic hydrocarbon ring or substituted or unsubstituted heterocycle, and two X′s are the same kind of substituent represented by any one of the following general formulas (B1) to (B3), in which the number of carbon atoms of the two X 1 s are the same as or different from each other; or wherein eight R 3 s are the same or different and each independently represents a hydrogen atom, a methyl group, or an ethyl group, Y represents a group containing at least one substituted or unsubstituted aromatic hydrocarbon ring or substituted or unsubstituted heterocycle, and X 2 , X 3 , X 4 and X 5 are the same kind of substituent that is represented by any one of the following general formulas (B1) to (B3), in which the number of carbon atoms of X 2 , X 3 , X 4 and X 5 are the same as or different from each other, wherein n 1 is an integer of 3 to 6, n 2 is an integer of 3 to 8, m is an integer of 0 to 3, Z′ represents a hydrogen atom or a methyl group, and Z 2 represents a hydrogen atom, a methyl group or an ethyl group.
