TECHNOLOGY FOCUS - IMAGING AND COMMUNICATION - Preferred Process: The reaction mixture is deposited via ink jet printing.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The atom of an element that is not carbon is hydrogen, oxygen, nitrogen, silicon, phosphorus, selenium, fluorine, boron or sulfur.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - The segments have a core comprising carbon, nitrogen, silicon, phosphorus atomic cores, alkoxy cores, aryl cores, carbonate cores, carbocyclic cores, carbobicyclic cores, carbotricyclic cores or oligothiophene cores. The linkers are 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 or carbonates linkers.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The SOF possesses thermal stability at temperatures of higher than 400 degrees C. The SOF is porous, and has an aspect ratio of greater than 30:1 and a thickness of greater than 20 Angstrom . The SOF comprises: many layers, which are chemically or physically attached; or at least one atom of an element that is not carbon. The segments comprise the first segment type and a second segment type, and the linkers comprise linkers of the first linker type and a second linker type. EXAMPLE - Benzene-1,4-dimethanol (0.47 g) and N4,N4,N4',N4'-tetrakis(4-(methoxymethyl)phenyl)biphenyl-4,4'-diamine (1.12 g), and 1-methoxy-2- propanol (17.9 g) were mixed to form a mixture. The mixture was shaken and heated to 60 degrees C, until a homogenous solution resulted. Upon cooling to room temperature, the solution was filtered through a polytetrafluoroethylene membrane (0.45 micron). To the filtered solution, an acid catalyst delivered as para-toluenesulfonic acid (0.31 g) in 1-methoxy-2-propanol was added to give the liquid containing reaction mixture. The reaction mixture was applied to the reflective side of a metalized MYLAR (RTM: Polyester film) substrate (A) using a constant velocity draw down coater outfitted with a bird bar having an 8 mil gap. The substrate (A) was rapidly transferred to an actively vented oven preheated to 130 degrees C, and left to heat for 40 minutes to obtain structured organic film.
