ABSTRACT:
Various embodiments of the present invention are directed to methods for manufacturing complex, anisotropic materials with desirable properties for information storage, processing, and display. Certain of these methods involve employing a magnetic field during manufacture to induce desired orientations of precursors, subunits, and/or molecular subassemblies. The applied magnetic field steers the precursors, subunits, and/or molecular subassemblies into desirable orientations while the precursors, subunits, and/or molecular subassemblies are assembled or self-assemble into a complex, anisotropic material. One embodiment of the present invention is a class of new, complex, well-ordered, network-like materials that include a ferromagnetic-material-based framework in which organic and/or organometallic compounds are organized. The ferromagnetic-molecule-based framework provides a scaffold for assembling the stable, precisely separated layers of organic and/or organometallic compounds and maintaining the layers of organic and/or organometallic compounds in well-ordered, anisotropic arrangements. Additional embodiments of the present invention are directed to methods for manufacturing the new ferromagnetic-molecule-based, network-like materials.
