In the title compound, C₃₈H₃₇NO₃, the pyran ring has an envelope conformation with the quaternary C_q atom as the flap atom. The dihedral angle formed between the methoxyphenyl group and the naphthalene ring system is 67.32 (6)°. The ethylamino groups lie to the same side of the plane through the phenyl ring and form dihedral angles of 84.6 (3) and 75.8 (2)° with it.

Comment top

The synthesis and applications of the organic photochromic and thermochromic dyes has become of great interest (Kumar et al., 1995; Gemert & Selvig, 2000; Nelson et al., 2002; Gabbutt et al., 2003, 2004). For example, they may be useful as optical transmission materials for ophthalmic glasses and lenses. They also have potential use for optical storage of optical disks or memories (Crano & Guglielmetti, 1999). In particular, benzo- and naphtho-pyrans have been commercialized as photochromic plastic sunglasses in the early 1990's. In our group, research has focused on the development of novel photochromic benzo- and naphtho-pyrans (Kim et al., 2010, 2011; Do et al., 2011). Herein, we report the crystal structure of N,N-diethyl-4-(9-methoxy-6-(4-methoxyphenyl)-5-methyl-2-phenyl-2H- benzo[h]chromene-2-yl)benzenamine (Fig. 1) as a new photochromic material. The –C2—O1—C12—C11—C4—C3- pyran ring has an envelope conformation with the quaternary C2 atom out of the plane, the dihedral angle is 38.7 (2)°, C2—O1 is 1.456 (3) Å and C2—C3 is 1.506 (3) Å. The dihedral angle formed between the methoxyphenyl group and the naphthalen ring of the naphthopyran substituent is 67.32 (6) °. The ethylamino groups of the diethylaminophenyl substituent form dihedral angles of 75.8 (2) and 84.6 (3) ° with the plane through the phenyl ring.

Experimental top

A solution of 7-methoxy-4-(4-methoxyphenyl)-3-methylnaphthalen-1-ol (10 g, 0.04 mol) and 1-(4-diethylaminophenyl)-1-phenylprop-2-yn-1-ol (11.18 g, 0.04 mol) in anhydrous toluene (500 ml) containing acidic alumina (32.6 g, 0.32 mol) was refluxed for 4 h. The cooled resulting solution was filtered and the alumina residue washed well with toluene. The organic layer was washed with aqueous NaOH and extracted with ethyl acetate (350 ml) and washed with water. The extracts were dried with anhydrous MgSO₄ and evaporated to give a crude orange oil. This was purified by silica gel column chromatograpy using 10% ethyl acetate/15% toluene in hexane as eluent. The purified yellow oil was solidified on trituration with ethyl ether. The solid obtained was suction filtered, washed with ethyl ether and air dried (yield: 6.2 g, 28%). Single crystals were obtained by recrystallization from its ethyl acetate solution.

Special details top

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.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
