A well known double brominated naphthalene intermediate

leads to 1,8-diarylnaphthalenes in application of optoelectronic devices and chiral molecules studies.


Specifications | MSDS | Literature and Reviews


1,8-Dibromonaphthalene (1,8-DBN), CAS number 17135-74-9, is a symmetrical double bromo-substituted naphthalene with two bromos sitting at the naphthalene ring mirroring each other along the joining carbons. 1,8-Dibromonaphthalene is the building block for 1,8-diarylnaphthalenes, a fascinating class of strained organic molecules.

1,8-Diarylnaphthalenes are great example of strained organic molecules that have unusual parallel face-to-face arrangement of two peri-aryl rings in close proximity almost perpendicular to the central naphthalene backbone. 1,8-Diarylnaphthalenes show great potential in highly efficient photoluminescent blue and green OLEDs, chiral ligands and sensors, nonlinear optic chromophores, stereo-dynamic switches and other optoelectronic devices.
