APPLICATIONS
Carbazole, azafluorene, is a group of organic heterocyclic compounds containing nitrogen atom in dibenzopyrrole system; white crystalline solid, insoluble in water, melts at 244 C. Carbazole and its derivatives are widely used as an intermediate in synthesis of pharmaceuticals, agrochemicals, dyes, pigments and other organic compounds. Carbazole is the basic substance of fluorescent properties. Due to extended pi-electron bond, carbazole is used in luminescence chemistry as a photosensitizing and additional charge transport material. 4,4'-Bis(carbazol-9-yl)biphenyl is used as an OLED hole transport material. Poly(9-vinylcarbazole) is an organic semiconductot. Organic electroluminescence materials have lead to the rapid development of photovoltaic and display devices. Carbazole structure is a motif in pharmaceuticals such as carvedilol used to treat high blood pressure and to prevent cardiac arrhythmias and angina.
