Claims46
An organic photosensitive optoelectronic device comprising a donor material and/or an acceptor material comprising at least one nonplanar porphyrin of formula (I),
- wherein
- M is selected from the group consisting of Sc, Y, La, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Tc, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Al, Ga, In, Tl, Si, Ge, Sn, Pb, P, As, Sb, Bi, S, Se, Te, Po, Cl, Br, I, At, lanthanides, actinides and 2H;
- R′ is independently selected from the group consisting of a Cl atom, Br atom, I atom, At atom, and a chemical group comprising a valence atom attached to the meso carbon atom of the porphyrin, wherein the valence atom is selected from the group consisting of B, C, N, O, Si, P, S, Ge, As, Se, In, Sn, Sb, Te, Tl, Pb, Bi and Po;
- and
- R is independently selected from the group consisting of a Cl atom, Br atom, I atom, At atom, and a chemical group comprising a valence atom attached to a β carbon atom of a pyrrole ring, wherein the valence atom is selected from the group consisting of B, C, N, O, Si, P, S, Ge, As, Se, In, Sn, Sb, Te, Tl, Pb, Bi and Po, alternatively two adjacent R groups attached to the same pyrrole ring together with the two β carbon atoms of the pyrrole ring form a carbocyclic group or heterocyclic group,
- wherein the organic photosensitive optoelectronic device is a photovoltaic cell.
A method for fabricating an organic photosensitive device, comprising providing a donor material and an acceptor material, wherein the donor material and/or the acceptor material comprises at least one nonplanar porphyrin of formula (I),
- wherein
- M is selected from the group consisting of Sc, Y, La, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Tc, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Al, Ga, In, n, Si, Ge, Sn, Pb, P, As, Sb, Bi, S, Se, Te, Po, Cl, Br, I, At, lanthanides, actinides and 2H;
- R′ is independently selected from the group consisting of a Cl atom, Br atom, I atom, At atom, and a chemical group comprising a valence atom attached to the meso carbon atom of the porphyrin, wherein the valence atom is selected from the group consisting of B, C, N, O, Si, P, S, Ge, As, Se, In, Sn, Sb, Te, Tl, Pb, Bi and Po;
- and
- R is independently selected from the group consisting of a Cl atom, Br atom, I atom, At atom, and a chemical group comprising a valence atom attached to a β carbon atom of a pyrrole ring, wherein the valence atom is selected from the group consisting of B, C, N, O, Si, P, S, Ge, As, Se, In, Sn, Sb, Te, Tl, Pb, Bi and Po, alternatively two adjacent R groups attached to the same pyrrole ring together with the two β carbon atoms of the pyrrole ring form a carbocyclic group or heterocyclic group;
- and
- making the organic photosensitive optoelectronic device comprising putting the donor material in contact with the acceptor material,
- wherein when both the donor material and acceptor material comprise at least one nonplanar porphyrin of formula (I), the at least one nonplanar porphyrin in the donor material is different from the at least one nonplanar porphyrin in the acceptor material.
