Specifications | MSDS | Literature and Reviews


1,4-Dibromonaphthalene (1,4-DBN), CAS number 83-53-4, is a bis-brominated naphthalene at 1,4-positions. 1,4-dibromonaphthalene can be obtained by the treatment of 1-bromonaphthalene with bromine in dichloromethane at -30 °C in high yield.

1,4-Dibromonaphthalene is well known as a triplet excitation acceptor with useful phosphorescent properties. It is also an useful intermediate for the synthesis of other 1,4-dibromonaphthalene derivatives in drug discovery such as enzyme-inhibitory, antifungal, antibacterial, anticancer, anti-inflammatory, antiallergic, phenols, amines,  coordination chemistry and organic electronic devices. Ambipolar deep-blue emitter, 4,4′-bis(4-(1-(4-(tert-butyl)phenyl)-1H-phenanthro[9,10-d]imidazol-2-yl)phenyl)-1,1′-binaphthalene (2NBTPI), derived from 1,4-dibromonaphthalene, demonstrates spatially separated HOMO and LUMO orbits, a high thermal stability and deep blue emission in OLED device.
