Abstract
Abstract Methods and compositions involving two-dimensional ordering of organic polar solvent soluble organic macromolecules. Lipid monolayer forming molecules are bound covalently or non-covalently to organic macromolecules soluble in polar solvents, whereby the macromolecules are allowed to become oriented in two-dimensions to form an ordered, low free energy, including crystalline, layer of macromolecules. The macromolecules may then be further combined with other moieties to create additional layers, to be cross-linked or otherwise modified, andlor separated from the lipid monolayer. The resulting ordered layers can be used for a variety of purposes, in crystallographic techniques for structure determination and structural relationship determinations, in optics, as polymers, films, and the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A method for ordering molecules in a lower free energy state as a monomolecular layer, wherein said molecules are characterized by being at least partially soluble in a polar medium, capable of forming an ordered array, capable of binding to a surfactant having lipophilic and hydrophilic regions, wherein said surfactant includes means for binding to said molecule in said hydrophilic region; said method comprising: combining under binding conditions a solution of said molecules in a polar solvent with a monolayer of said surfactant situated at about the surface of said solution, whereby said molecules bind to said surfactant; and incubating the mixture for a time sufficient to allow for ordering of said molecules as a monomolecular layer.
Claim 2
Independent Claim
117 words
A method for ordering molecules in a lower free energy state as a monomolecular layer, wherein said molecules are characterized by being at least partially soluble in a polar medium, capable of forming an ordered array, capable of binding to a surfactant having lipophilic and hydrophilic regions, wherein said surfactant includes means for binding to said molecule in said hydrophilic region; said method comprising: combining under binding conditions a solution of said molecules in a polar solvent with a monolayer of said surfactant situated at about the surface of said solution, whereby said molecules bind to said surfactant; and incubating the mixture for a time sufficient to allow for ordering of said molecules as a monomolecular layer.
