4-NITRO-2-(TRIFLUOROMETHYL)BENZOIC ACID is white to light yellow crystal powder. It is a useful chemical material.
InChI:InChI=1/C8H4F3NO4/c9-8(10,11)6-3-4(12(15)16)1-2-5(6)7(13)14/h1-3H,(H,13,14)
The invention provides a fluorine-containing aromatic diamine compound and a preparation method thereof, and a fluorine-containing polyimide compound and a preparation method thereof. The polyimide compound prepared from the fluorine-containing aromatic diamine compound provided by the invention is good in solubility, relatively high in transmittance and good in mechanical property.
The present invention provides a novel diamine compound capable of producing a polymer which exhibits greatly enhanced mechanical properties and heat resistance while maintaining transparency. A film including a polymer produced using the diamine compound has excellent transparency, heat resistance, mechanical strength and flexibility, and thus can be used in various fields, such as in a device substrate, a display cover substrate, an optical film, an Integrated circuit (IC) package, an adhesive film, a multi-layer flexible printed circuit (FPC), a tape, a touch panel and an optical disc protection film, and the like.
