Data storage materials
The invention provides metal-organic complexes useful for storing information in an information storage system. The invention also provides methods for forming such complexes on a substrate, as well as apparatuses and systems comprising such complexes.
1. A metal-organic complex comprising two or more metal atoms wherein one metal atom is associated with a first organic group comprising one or more double bonds and another metal atom is associated with a second organic group comprising one or more double bonds such that one or more double bonds in the first organic group are spatially oriented to react with one or more double bonds in the second organic group.
2. The complex of claim 1 that comprises the following structure:
wherein:
the group MAM is a metal-organic group comprising at least two metal atoms M;
each R 1 is independently an organic group comprising one or more double bonds; and
the dashed lines designate an association between R 1 and M.
3. A metal-organic complex comprising two or more metal atoms wherein one metal atom is associated with a first organic group comprising one or more double bonds and another metal atom is associated with a second organic group comprising one or more double bonds such that one or more double bonds in the first organic group are spatially oriented to react with one or more double bonds in the second organic group wherein each metal atom is independently Zn.
4. The complex of claim 2 wherein each group MAM is a Schiff-base complex.
5. A metal-organic complex comprising two or more metal atoms wherein one metal atom is associated with a first organic group comprising one or more double bonds and another metal atom is associated with a second organic group comprising one or more double bonds such that one or more double bonds in the first organic group are spatially oriented to react with one or more double bonds in the second organic group wherein the complex comprises the following structure:
wherein:
the group MAM is a metal-organic group comprising at least two metal atoms M; each R 1 is independently an organic group comprising one or more double bonds; and the dashed lines designate an association between R 1 and M;
wherein each group MAM is a Schiff-base complex and wherein one or more of the groups MAM has the following structure:
wherein:
each R a , R b , and R c is independently hydrogen, halo, nitro, cyano, C 1-6 alkyl, C 1-6 alkoxy, C 1-6 alkanoyl, C 1-6 alkanoyloxy, C 1-6 alkoxycarbonyl, trifluoromethyl, aryl(C 1-6 alkyl), carboxy, or trifluoromethoxy;
each n is independently 0, 1, 2, or 3; and
each R d and R e is independently hydrogen or C 1-6 alkyl; or R d and R e together with the atoms to which they are attached form a 5, 6, 7, or 8 membered saturated or unsaturated ring.
6. The complex of claim 5 wherein R b is C 1-6 alkyl, benzyl, bromo, or C 1-6 alkoxy.
7. The complex of claim 1 which is a crystalline solid.
