9,9-bis(4-amino-3-fluorophenyl)fluorene is also named as 4,4'-(9h-fluorene-9,9-diyl)bis(2-fluoroaniline); 9,9-bis(3-fluoro-4-aminophenyl)fluorene(FFDA).Fluorene is one of the elements contained in coal tar. When various benzene rings are bonded to fluorene, a fluorene derivative is obtained. A fluorene derivative has a three-dimensional configuration called a cardo structure. As the cardo structure contains a lot of aromatic rings, this structure has a high refractive index and high heat resistance. In addition, as each of the aromatic rings faces in a different direction, the optical anisotropy is reduced, and birefringence becomes weaker. Our company produces various types of fluorene derivatives. Polyester resin is used for digital camera lenses, acrylate for various types of liquid crystal films, and epoxy for thermosetting resin.
