2. The SOF of claim 1 , wherein the SOF possesses thermal stability at temperatures higher than 400° C.
3. The SOF of claim 1 , wherein the SOF is porous.
4. The SOF of claim 1 , wherein the SOF is capable of reversible guest uptake.
5. The SOF of claim 1 , wherein the SOF has an aspect ratio greater than about 30:1.
6. The SOF of claim 1 , wherein the SOF comprises a plurality of layers.
7. The SOF of claim 6 , wherein the plurality of layers are chemically attached.
8. The SOF of claim 7 , wherein the SOF has a thickness greater than about 20 Angstroms.
9. The SOF of claim 6 , wherein the plurality of layers are physically attached, and the SOF has a thickness greater than about 20 Angstroms.
10. The SOF of claim 1 , wherein the plurality of segments consists of segments having the first segment type, and the plurality of linkers consists of linkers of the first linker type.
11. The SOF of claim 1 , wherein the plurality of segments comprises at least the first segment type and a second segment type; the plurality of linkers comprises at least the first linker type and a second linker type; or the plurality of segments comprises at least the first segment type and a second segment type and the plurality of linkers comprises at least the first linker type and a second linker type.
12. The SOF of claim 1 , wherein the plurality of segments have a core selected from the group consisting of carbon, nitrogen, silicon, or phosphorous atomic cores; alkoxy cores; aryl cores; carbonate cores; carbocyclic cores; carbobicyclic cores; carbotricyclic cores; and oligothiophene cores.
13. The SOF of claim 1 , wherein the plurality of linkers are selected from the group consisting of single atom linkers, single covalent bond linkers, double covalent bond linkers, ester linkers, ketone linkers, amide linkers, amine linkers, imine linkers, ether linkers, urethane linkers, and carbonates linkers.
14. The SOF of claim 1 , wherein the SOF comprises at least one atom of an element that is not carbon.
15. The SOF of claim 14 , wherein the at least one atom of an element that is not carbon is selected from the group consisting of hydrogen, oxygen, nitrogen, silicon, phosphorous, selenium, fluorine, boron, and sulfur.
16. The SOF of claim 1 , wherein the SOF is a free-standing SOF.
17. A structured organic film (SOF) comprising a plurality of segments including at least a first segment type and a plurality of linkers including at least a first linker type arranged as a covalent organic framework (COF), wherein the SOF is a film, and the first segment type and/or the first linker type comprises at least one atom that is not carbon.
18. The SOF of claim 17 , wherein the at least one atom of an element that is not carbon is selected from the group consisting of hydrogen, oxygen, nitrogen, silicon, phosphorous, selenium, fluorine, boron, and sulfur.
19. A process for preparing a structured organic film (SOF) comprising:
(a) preparing a liquid-containing reaction mixture comprising a plurality of molecular building blocks each comprising a segment and a number of functional groups;
(b) depositing the reaction mixture as a wet film; and
(c) promoting change of the wet film to form a dry SOF; wherein the reaction mixture is deposited by spin coating, blade coating, web coating, dip coating, cup coating, rod coating, screen printing, ink jet printing, spray coating, or stamping.
20. The process of claim 19 , wherein the reaction mixture is deposited via ink jet printing.
