1. A fluorinated 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 at least the first segment type contains fluorine. 2. The SOF of claim 1, wherein the plurality of segments further comprises a second segment type containing fluorine that is different in structure from the first segment type. 3. The SOF of claim 1, wherein from about 30% by weight to about 70% by weight of the segments of the SOF are fluorinated. 4. The SOF of claim 1, wherein the fluorine content of the SOF is from about 5% to about 65% by weight of the SOF. 5. The SOF of claim 1, wherein fluorine distribution is patterned within the SOF. 6. The SOF of claim 1, wherein fluorine is distributed randomly within the SOF. 7. The SOF of claim 1, wherein fluorine is distributed non-uniformly within the thickness of the SOF. 8. The SOF of claim 1, wherein the SOF further comprises a capping unit. 9. The SOF of claim 1, wherein the SOF is a substantially pinhole-free film. 10. The SOF of claim 1, wherein the SOF is a composite SOF. 11. The SOF of claim 1, wherein the SOF has the added functionality of electroactivity. 12. The SOF of claim 1, wherein the first segment type is selected from the group consisting of 2,2,3,3,4,4,5,5-octafluoro-1,6-hexanediol, 2,2,3,3,4,4,5,5,6,6,7,7-dodecanfluoro-1,8-octanediol, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9-perfluorodecane-1,10-diol, (2,3,5,6-Tetrafluoro-4-Hydroxymethyl-Phenyl)-Methanol, 2,2,3,3-Tetrafluoro-1,4-Butanediol, 2,2,3,3,4,4-Hexafluoro-1,5-Pentanediol, 2,2,3,3,4,4,5,5,6,6,7,7,8,8-Tetradecafluoro-1,9-Nonanediol. 13. The SOF of claim 1, wherein the SOF is a defect-free SOF. 14. The SOF of claim 1, wherein the water contact angle on the surface of the SOF is at least 80 degrees. 15. The SOF of claim 1, wherein the presence of fluorine segments modulates the surface energy of the SOF. 16. A process for preparing a fluorinated structured organic film, comprising: (a) preparing a liquid-containing reaction mixture comprising: a plurality of molecular building blocks including at least a first segment type and a number of functional groups, wherein the first segment type contains fluorine;(b) depositing the reaction mixture as a wet film; and(c) promoting change of the wet film to form a dry SOF. 17. The process of claim 16, wherein the liquid-containing reaction mixture is a homogeneous solution. 18. The process of claim 16, wherein the fluorine content of the dry SOF is from 5% to 65%. 19. The process of claim 16, wherein from about 30% by weight to about 70% by weight of the segments of the dry SOF are fluorinated. 20. A fluorinated 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 framework of the SOF comprises fluorine-containing capping units bonded thereto via linker groups.
