2,3-Dibromonaphthalene (2,3-DBN), CAS number 13214-70-5, is another useful intermediate and isomer of dibromonaphthalene with two heavy bromo substituents sitting next to each other around the naphthalene ring.

X-ray diffraction analysis shows that the crystal structure of 2,3-dibromonaphthalene is ordered where the weak and directional forces generate the herringbone packing of the constituting molecules. For this reason, 2,3-dibromonaphthalene is employed as a suitable host for fluorescent  polycyclic aromatic hydrocarbons (PAH) molecules. Single molecules of terrylene in 2,3-dibromonaphthalene crystallise also in a herringbone pattern, directed by the 2,3-dibromonaphthalene host.
