An isomer of dibromonaphthalene and building block for organic semiconductors
Used in application of OLEDs and OFETs.
1,5-Dibromonaphthalene (1,5-DBN), CAS number 7351-74-8, one of the many isomers of dibromonaphthalene, can be obtained by direct selective electrophilic substitution of 1-bromonaphthalene.
1,5-di(anthracen-2-yl)naphthalene (1,5-DAN), prepared from 1,5-dibromonaphthalene, has strong blue solid-state emission with high-efficiency charge transport ability. The single-crystal mobility of 1,5-DAN is as high as 8.41 cm2 V-1 s-1 with a photoluminescence quantum yield up to 20.54%. Unlike the 2,6-positions substituted molecules, 1,5-DAN displays a blue emission caused by the large torsion angle between the substituents and core [1].
