Abstract
A method of stamping of molecular patterns and/or devices based on the reversible self-assembly of molecules, particularly organic molecules is disclosed. This method is suitable for the stamping of almost any nanofabricated device and can be used to transferring a large amount of pattern information from one substrate to another at the same time.

A method of forming a complement image of a master, comprising the steps of:
- a) providing a master that comprises a first set of molecules bound to a first substrate to form a pattern;
- b) assembling via attractive forces or bond formation a second set of molecules on the first set of molecules, wherein each molecule in the second set of molecules comprises:
- i) a reactive functional group;
- and
- ii) a recognition component that is attracted to or binds to one or more of the first set of molecules;
- c) contacting the reactive functional group of the second set of molecules with a surface of a second substrate, thereby forming a bond between the second set of molecules and the second substrate;
- d) breaking the attractive force or bonds between the first set of molecules and the second set of molecules, thereby forming a complement image of the master;
- and
- e) optionally repeating steps b) through d) one or more times.

A method of forming a reproduction of a master, or portion thereof, comprising the steps of:
- a) providing a master that comprises a first set of molecules bound to a first substrate to form a pattern;
- b) assembling via bond formation a second set of molecules on the first set of molecules, wherein each molecule in the second set of molecules comprises:
- i) a reactive functional group;
- and
- ii) a recognition component that binds to the first set of molecules;
- c) contacting the reactive functional group of the second set of molecules with a surface of a second substrate, thereby forming a bond between the second set of molecules and the second substrate;
- d) breaking the bonds between the first set of molecules and the second set of molecules, thereby forming a complement image of the master;
- e) assembling via bond formation a third set of molecules on the second set of molecules of the complement image, wherein each molecule in the third set of molecules comprises:
- i) a reactive functional group;
- and
- ii) a recognition component that binds to the second set of molecules;
- f) contacting the reactive functional group of the third set of molecules with a surface of a third substrate, thereby forming a bond between the third set of molecules and the third substrate;
- g) breaking the bonds between the second set of molecules and the third set of molecules, thereby forming the reproduction of the master, or portion thereof;
- and
- h) optionally repeating steps e) through g) one or more times.
