Comment top

Carbazole - based materials had been investigated for their electrical and optical properties. Especially, introduction of substituents on the 3- and 6-positions of carbazole represents a possible approach for designing carbazole-based photorefractive materials (Yang et al., 2005). The title molecule that we has designed and synthesized is a good intermediate and penetratingly investigated. In the title molecule (Fig.1), the bond lengths and angles show normal values (Chen et al., 2009; Zhou et al., 2007, 2008). Two thiophene rings are twisted out of the plane of the center pyrrole ring and the dihedral angles are 32.4 (2)° and 9.8 (2)°, respectively. In the crystal structure of title compound (Fig.2), the neighboring molecules form a centrosymmetric dimer by C17—H17···I1i (symmetry code: (i) -x, 3-y, 2-z). The neighboring dimers are stacked through weak π···π interaction and the face-to-face distance between two neighboring thiophene rings is 3.57 (4)Å.

Experimental top

Preparation of 9-ethyl-3,6-diiodocarbazole: 9-ethylcarbazole (10 g, 51 mmol) and anhydrous ethanol (150 ml) were added to a three-necked flask equipped with a magnetic stirrer, a reflux condenser and an isobaric dropping funnel. ICl (20 g, 123 mmol)/ethanol (20 ml) was added to the mixture at 353 K. The reaction mixture was refluxed for 2 h, cooled to room temperature and filtered. The grey needle crystals (20.52 g, yield 90%) were obtained and washed with ethanol.

Preparation of 9-ethyl-3,6-di(2-thienyl)carbazole: a 80 ml three-necked round-bottomed flask was charged with of 9-ethyl-3,6-diiodocarbazole (3.00 g, 6 mmol), 10 ml of DMF, 10 ml of Et3N and thiophen-2-yl-boronic acid (2.55 g, 20 mmol). A catalytic amount of Pd(OAc)2 was added to the stirring solution at 343 K after 9-ethyl-3,6-diiodocarbazole was completely dissolved under nitrogen. The solution was refluxed for 6 h at 403 K. At the end of the reaction was judged by TLC analysis. The solution was cooled to room temperature and dissolved in 200 ml CH2Cl2, then washed with water (3× 200 ml), dried over anhydrous MgSO4, brown column crystals were obtained (2.00 g, yield 80% ).

Preparation of 9-ethyl-3,6-di{2-[(5-iodo)thiophene]-yl}carbazole: a 50 ml round-bottomed flask was charged with 9-ethyl-3,6-di(2-thienyl)carbazole (0.13 g, 0.3 mmol) and 9 ml of acetone. A N-iodosuccinimide (0.42 g, 1.9 mmol) dissolved in 4 ml acetone and was added to the stirring solution at room temperature after 9-ethyl-3,6-di(2-thienyl)carbazole was completely dissolved. At the end of the reaction was judged by TLC analysis after 4 h. The solution was dissolved in 100 ml CH2Cl2, then washed with water (3× 200 ml), dried over anhydrous MgSO4. The organic layer was concentrated in vacuum, the orange suspended solution was decanted out of the flask after 3 ml ethanol was added, green crystals were obtained (0.14 g, yield 54%).

Refinement top

All hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93–0.97Å and Uiso(H) = 1.2–1.5 Ueq(C). At the end of the refinement, the highest peak in the electron–density map was 0.93Å from I2 and the deepest hole was 0.73 Å from I2.

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