The crystal of the title compound, C₆₀H₃₈N₂O₂, which crystallizes in the monoclinic space group P2₁/n, was obtained by thermal evaporation of a 1:1 dichloromethane and hexanes solution of the pure compound. The crystal structure is stabilized by π–π interactions between benzo[def]carbazole moieties and carbonyl–carbonyl interactions between the two acetyl groups.

Keywords: crystal structure; benzo[def]carbazole; π–π stacking; fluorescence; dual emission.

1. Chemical context

For recent background literature on the chemistry of related carbazole-derived compounds and their applications, including syntheses of bioactive carbazoles, see: (Chakraborty et al., 1965 ; Bondock et al., 2019 ) and references cited therein. The syntheses of related benzo[def]carbazoles are described by Pocock et al. (2021 ) and Geng et al. (2016 ). For applications of benzo[def]carbazole derivatives, see: Vespa et al. (2018 ), Atakan & Gunbas (2016 ) and Myśliwiec et al. (2015 ).

The photophysical properties of 4H-benzo[def]carbazole have been studied over the past few decades (Bender et al., 1964 ; Zander et al., 1966 ; Favini et al., 1971 ; Horaguchi et al., 1980 ). The spectra show that the wavelengths of absorption and emission maxima are in the ranges 230–410 nm and 345–520 nm, respectively, at different temperatures and for different solvents. The effect of the solvent on absorption and fluorescence bands as well as comparisons with theoretical expectations have been used to estimate the dipole moment of the first excited state. Geng et al. (2016) reported the optimized geometry, electron-density distributions, and HOMO and LUMO of carbazole and 4H-benzo[def]carbazole. Changes in the HOMO–LUMO gap (Eg) and the design of molecules for material applications can be realized by comparing frontier molecular orbitals, HOMO and LUMO energy levels, and exploring their electron-density maps.

In order to obtain the benzo[def]carbazole 2 efficiently, we utilized the pathway through the conversion of diphenylphenanthrene 1 to N-acetyl benzo[def]carbazole 2. We obtained N-acetyl carbazole 2 in quantitative yield utilizing Buchwalds' method by treatment of diphenylphenanthrene 1 as a substrate in the presence of Pd(OAc)₂ (10 mol %), NaOAc (1.0 equiv.), Cu(OAc)₂ (2.0 equiv.) and powdered molecular sieves in toluene under oxygen at 393 K for 24 h. Single crystals of 2 were grown from the a mixture of hexanes and DCM (v/v = 1:1) at room temperature by slow thermal evaporation.

2. Structural commentary

Compound 2 crystallizes in the monoclinic space group P2₁/n with two independent molecules in the asymmetric unit. The atomic labelling scheme is shown in Fig. 1. The C—C bond lengths are within the expected values known for aromatic systems (Allen et al., 1987 ).

In the structure of 2, both independent conformers occupy their own coordinates in the asymmetric unit, but are in the same configuration. On the other hand, owing to the space group of the title compound, P2₁/n, which is centrosymmetric, both molecules will produce two identical configurations that are 180° inverted from each other. In the stereoscopic view, we can observe that the phenyl group and the phenyl alkynyl moiety in the two independent conformers have different dihedral angles with respect to the benzo[def]carbazole, which are 22.2 (1), 25.7 (2)° and 50.8 (2), 59.7 (2)°, respectively.

3. Supramolecular features

In the crystal, there are no classical hydrogen bonds present and the crystal packing of 2 (Fig. 2) is mainly determined by intermolecular π–π interactions between the benzo[def]carbazole moieties with centroid–centroid distances of 3.795 (2) to 4.553 (1) Å (Fig. 3a, grey dashed line), acetyl–acetyl dipolar interactions of 3.459 (3) to 3.689 (3) Å (Fig. 3a, blue dashed line), C—H⋯π interactions of 2.935 (2) to 3.314 (3) Å (Fig. 3b, green dashed line), and π–π interactions with centroid–centroid distances of 3.801 (2) to 5.672 (2) Å (Fig. 3b, red dashed lines) between phenyl alkynyl moieties. Specifically, the crystal is stabilized by the phenyl groups of the alkynyl moiety, which interacts weakly with each other (Fig. 3b, red dashed lines) through π–π stacking. Furthermore, the phenyl group also interacts with another neighboring phenyl moiety and with the phenyl alkynyl moiety through C—H⋯π interactions (Table 1). In addition, π–π stacking and carbonyl–carbonyl interactions with δC⁺ and δO⁻ between the two acetyl groups are observed. The molecules are ordered into infinite ribbons extending along the [001] direction through alternating intermolecular C—H⋯π and π–π stacking interactions.

4. Database survey

A search of the Cambridge Structural Database (WebCSD accessed 21 April 2022; Groom et al., 2016 ) results in over a thousand carbazole derivatives of which 45 are derivatives of benzo[def]carbazole. Most of the compounds are cyclized with the benzo moiety to the skeleton of benzo[def]carbazole. Of these, 31 molecular structures are derivatives of the main structure of phenanthro[1,10,9,8-cdefg]carbazole that is commonly used to design functional molecules, such as organic transistors or n-doped thermoelectric devices [KUTZUX (Cann et al., 2020 ); ZAJMUW (Martell et al., 2021 )], white-light emissive material (ILIGIW; Chatsirisupachai et al., 2021 ), N-annulated perylene diimide for stable organic materials with unique optical, electronic, magnetic properties (MEHDUB; Wei et al., 2017 ), organic solar cells [NEXKOT (Ma et al., 2018 ); EZETOU (Hendsbee et al., 2016 )] and the green solvent processing of organic charge-transporting materials (HUVQEX; Harding et al., 2020 ). Other compounds have benzo[def]carbazole derivatives as the skeleton, for instance, 4,5-iminophenanthrene (IMNPHN; Ern et al., 1971 ), aka 4H-benzo[def]carbazole, capped [3]cyclo(2,6)benzo[def]carbazoledichloromethane solvate (ROZQAA; Myśliwiec et al., 2015), picenoporphyrins [QUQYAC01 (Nath et al., 2003 ); QUQYAC (Aihara et al., 2001 )] and 4H-naphtho[1,2,3,4-def]carbazole (IWOBEE; Pocock et al., 2021). In addition, there is no alkynyl phenyl group on C8 and a phenyl group on C9 of the benzo[def]carbazole as in the title compound in any structure found in the WebCSD search. The title compound is the only one with an N-acetyl group attached to the benzo[def]carbazole unit.

5. Synthesis and crystallization

To a dried reaction tube, phenanthrene 1 (0.1 mmol), Pd(OAc)₂ (2.25 mg, 0.01 mmol), Cu(OAc)₂ (36.3 mg, 0.2 mmol), NaOAc (16.4 mg, 0.2 mmol) and powdered molecular sieves (40 mg, activated 3 Å) were added under air and covered with a septum. The tube was evacuated and refilled with N₂. Under a positive N₂ pressure, toluene (2 mL) was added via a syringe followed by degassing under a weak vacuum to this tube, and it was refilled with O₂ three times. The reaction mixture was sealed and stirred at 293 K for 24 h under an O₂ atmosphere. After completion of the reaction, the solution was cooled to room temperature and diluted with ethyl acetate followed by filtration through a thin pad of Celite. The crude product was purified by flash chromatography (hexanes/EtOAc) on silica gel to afford N-acetyl benzo[def]carbazole 2. Crystals of the title compound were obtained by thermal evaporation of the pure compound from a 1:1 solution of dichloromethane and hexanes.

6. Refinement

Special details top

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