9,10-Di(1'-naphthyl)anthracene was prepared by a literature procedure (Kwon et al., 2002; Lee et al., 2008). Bromonaphthalene and anthraquinone were commercially available from Aldrich and used as received. n-Buthyllithium (18 ml, 1.6 M in hexane) was slowly added at 195K to a THF (50 ml) solution of bromonaphthalene (4.9 g, 0.024 mol). Anthraquinone (2 g, 0.0096 mol) was added to the mixture and the solution was stirred for 3 h at room temperature. Aqueous 2 N HCl solution was added and the organic phase was separated. The organic phase was dried and potassium iodide (0.028 mol), sodium hypophosphite monohydrate (0.0576 mol), and acetic acid (100 ml) were added. The mixture was heated for 4 h under reflux. After cooling, the precipitate was collected, washed with plenty of water, and dried (yield 80%). The separation of two isomers, syn and anti, was successfully performed after several recrystallizations from toluene and xylene. The single crystal of anti form was grown in pyridine and hexane solution.

9,10-Dinaphthylanthracene has been widely used as a blue light emitting material in organic light emitting diodes (OLED) (Zhang et al., 2003; Raghunath et al., 2006). There are two σ-bond between naphthyl and anthracene moiety is so hindered. Since the two of 9,10-di(1'-naphthyl)anthracene, syn and anti, could have different physical properties such as electronic states, it is considered important to carry out studies on the isolation and characterization of the isomers. Herein we report the single of the anti form of 9,10-di(1'-naphthyl)anthracene. The molecular structure is shown in Fig. 1.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

9,10-Dinaphthylanthracene has been widely used as a blue light emitting material in organic light emitting diodes (OLED) (Zhang et al., 2003; Raghunath et al., 2006). There are two stereoisomers for 9,10-di(1'-naphthyl)anthracene because the single bond rotation about the σ-bond between naphthyl and anthracene moiety is so hindered. Since the two stereoisomers of 9,10-di(1'-naphthyl)anthracene, syn and anti, could have different physical properties such as electronic states, it is considered important to carry out studies on the isolation and characterization of the isomers. Herein we report the single crystal structure of the anti form of 9,10-di(1'-naphthyl)anthracene. The molecular structure is shown in Fig. 1.
In the title compound, (C34H22).2(C5H5N), the dihedral angle between anthracene and naphtyl mean planes is 83.96 (4)°. There is a crystallographic inversion center located in the middle of anthracene ring. The crystal structure is stabilized by weak intermolecular C—H···N and C-H···π interactions (Table 1, Fig. 2).
