Methods for making a substrate comprising structured organic film nano- to micro-features are disclosed. The methods for forming SOF micro-features may include: providing a substrate; discharging at least one droplet toward the substrate by an ink jet method, the at least one droplet including a plurality of molecular building blocks each comprising a segment and a number of functional groups; depositing the at least one droplet on the substrate; promoting a change in the deposited at least one droplet and forming at least one dry structured organic film (SOF) on the substrate.

The method of claim 1, wherein the viscosity of the reaction mixture is from about 2 cPs to about 30 cPs. 3. The method of claim 1, wherein the inkjet method is selected from the group consisting of thermal inkjet methods, piezoelectric inkjet methods, and continuous inkjet methods. 4. The method of claim 1, wherein the at least one droplet is charged. 5. The method of claim 1, wherein the SOF micro-feature is a dry SOF and is covalently bonded to the substrate. 6. The method of claim 1, wherein the substrate is a photoreceptor comprising an SOF as the outer layer. 7. The method of claim 6, wherein the SOF micro-features are covalently bonded to the SOF of the photoreceptor. 8. The method of claim 7, wherein the pattern results in a roughness on the surface of the photoreceptor. 9. The method of claim 7, wherein the pattern results in a roughness throughout the surface of the outer layer of the photoreceptor that lowers friction of the surface of the photoreceptor with a cleaning blade. 10. The method of claim 1, wherein the substrate further comprises an SOF micro-feature having a shape selected from the group consisting of lines, conic sections, regular polygons ridges, circles, rods, squares, triangles, polygons, and mixtures thereof formed at a predetermined position on the surface of the substrate. 11. A method for forming a structured organic film (SOF) micro-feature, the method comprising: providing a substrate;discharging a first one or more droplets toward the substrate by an ink jet method and depositing at least one of the first one or more droplets on a surface of the substrate at a first predetermined location, the first one or more droplets including a first reaction mixture comprising a first plurality of molecular building blocks;promoting a change in one or More of the at least one deposited droplets to form a plurality of SOF micro-features, each SOP micro-feature in the plurality of SOF micro-features 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) on the surface of the substrate; whereinthe plurality of SOF micro-features are arranged in a pattern on the surface of the substrate, the pattern including an array of protrusions or bumps in which the protrusions or bumps are positioned at predetermined distance away from the adjacent protrusions or bumps on the surface of the substrate, andthe substrate is a photoreceptor comprising an SOP as the outer layer. 12.

The method of claim 11, further comprising discharging a second one or more droplets toward the substrate by an ink jet method and depositing at least one of the second one or more droplets on a surface of the substrate at a second predetermined location, the second one or more droplets including a second reaction mixture comprising a second plurality of molecular building blocks. 15. The method of claim 14, wherein the viscosity of the second reaction mixture is from about 2 cPs to about 30 cPs. 16. The method of claim 14, wherein the first reaction mixture is not miscible with the second reaction mixture. 17. The method of claim 14, wherein the second plurality of molecular building blocks have a different chemical structure than the first plurality of molecular building blocks. 18. The method of claim 14, wherein the viscosity of the second reaction mixture is greater than the viscosity of the first reaction mixture, and the chemical structure of the second plurality of molecular building blocks is the same as the first plurality of molecular building blocks. 19. The method of claim 14, wherein the viscosity of the second reaction mixture is less than the viscosity of the first reaction mixture, and the chemical structure of the second plurality of molecular building blocks is the same as the first plurality of molecular building blocks. 20. The method of claim 11, wherein the substrate further comprises an SOF micro-feature having a shape selected from the group consisting of lines, conic sections, regular polygons, ridges, circles, rods, squares, triangles, polygons, and mixtures thereof formed at a predetermined position on the surface of the substrate.
