The use of carbazole
Carbazole, also known as 9 - nitrogen (m) fluorene (dibenzopyrrole), the formula for the C12H9N, molecular weight of 167.20. Carbazole is an important organic intermediate, in addition to the traditional use of dyes, pharmaceuticals and pesticide synthesis, the carbazole and its derivatives are widely used in the synthesis of photoelectric functional materials.
Carbazole can be used to produce dyes, pigments, photoconductors, photographic materials, specialty inks and so on. Use it to produce pigments permanent purple RL, widely used in automotive finish and high temperature plastic coloring, with high temperature, UV resistance advantages. With its production of dye vulcanization reduction blue RNX, Hai Chang blue excellent fastness indicators, in particular, excellent resistance to chlorine bleaching fastness, blue varieties are carbazole IDM, carbazole LR, carbazole LB, carbazole L3B , Black varieties have carbazole black D. It also produces carbazole bisoxazine violet, which is a violet pigment for use in paints, printing inks, carbon paper and so on. Carbazole for the production of sulfur reduction blue RNX, direct fast blue FFRL, FFGL and so on. Can also be made of leather, N-vinyl carbazole plastic, pesticide insecticide tetranitrocarbazole, carbazole and UV sensitive photo-sensitive film and so on. In addition, carbazole in the emerging photoelectric new material development has been more and more applications, the use of carbazole can be prepared organic nonlinear optical (NLO) materials, organic electroluminescence (OEL) materials, photorefractive materials, containing Carbazole chromophore bifunctional system, containing carbazole light folding small molecules such as glass.
