Abstract top

The title compound, C26H24BF2N3O, comprises a boron-dipyrromethene (BODIPY) framework and a phenolic Schiff base substituent group. The BODIPY unit is close to planar [maximum deviation from the least-squares plane = 0.040 (3) Å], and forms a dihedral angle of 80.38 (13)° with the meso-substituent phenyl ring and an angle of 56.57 (13)° with the phenolic ring in the extended substituent chain. An intramolecular O-H...N hydrogen bond is formed between the phenolic hydroxyl group and the Schiff base N-atom. The crystal studied was a non-merohedral twin with a BASF factor of 0.447 (3) for the two components.

Comment top

Among various fluorescent compounds, boron complexes, especially boron-dipyrromethene (BODIPY), show many photophysical advantages over other dyes, such as high absorption coefficients and fluorescence quantum yields, narrow emission spectra, excellent stability towards light and chemicals, enabling their applications in light harvesting, biological imaging and fluorescent probes (Boens et al., 2012). As part of our ongoing studies of fluorescent probes for metal ions, we report herein the crystal structure of the title compound, 10-(4-((2-hydroxybenzylidene)amino)phenyl)-5,5- difluoro-1,3,7,9-tetramethyl-5H-dipyrrolo[1,2-c:2',1'-f][1,3,2] diazaborinin-4-ium-5-uide, C26H24BF2N3O.

The title compound comprises essentially a C9BN2 (BODIPY) parent component and a phenolic Schiff base substituent group (Fig. 1). The bond lengths and angles are within normal ranges [B—F, 1.397 (4), 1.402 (4) Å and B—N, 1.528 (4), 1.541 (4) Å]. The BODIPY core is close to planar, with a maximum deviation from the least-squares plane of 0.040 (3) Å. The meso-substituted benzene ring defined by atoms C14–C19 is essentially perpendicular to this plane, forming a dihedral angle of 80.38 (13) ° with it. The phenolic ring in the extended substituent chain, defined by atoms C21–C26, forms a dihedral angle of 56.57 (13)° with the BODIPY plane. A moderately strong intramolecular O—H···N hydrogen bond is formed between the phenolic hydroxyl group and the Schiff base N-atom (Table 1). Weak non-classical intermolecular aromatic C—H···F hydrogen bonds extend the molecules into two-dimensional network structure lying parallel to [110] (Fig. 2).

Experimental top

The BODIPY precursor 10-(4-Aminophenyl)-5,5-difluoro-1,3,7,9-tetramethyl-5H-dipyrrolo [1,2 - c:2,,1,-f][1,3,2]diaza-borinin-4-ium-5-uide was synthesized according to the literature procedure (Lu et al., 2009). To a mixture of this compound (100 mg, 0.30 mmol) and 2-hydroxybenzaldehyde (50 mg, 0.40 mmol) in EtOH, one drop of trifluoroacetic acid was added. The reaction solution was heated at 353 K for 4 h, and the red precipitate was filtered and washed with ethanol to obtain the title compound. Yield: 80%. Red crystals. 1H NMR (400 MHz, CDCl3) δ (ppm.): 13.06 (s, 1H), 8.72 (s, 1H), 7.43 (dd, J = 12.4, 4.5 Hz, 4H), 7.36 (d, J = 8.0 Hz, 2H), 7.06 (d, J = 8.2 Hz, 1H), 6.98 (t, J = 7.5 Hz, 1H), 6.01 (s, 2H), 2.56 (d, J = 9.4 Hz, 6H), 1.46 (s, 6H). MALDI-TOF: m/z = 443.1 [M]+, 424.0 [M—F]+. Red single crystals suitable for X-ray analysis were obtained by dissolving the compound (0.10 g) in a hexane/dichloromethane (15 ml, v/v, 1/1) mixture and slowly evaporating the solvent at room temperature for a period of about one week.

Refinement top

Twinning was detected by TwinRotMat in PLATON (Spek, 2009) with a BASF factor of 0.45. A HKLF5 format reflection file was generated for the refinement, giving a final BASF factor of 0.447 (3). Hydrogen atoms were treated as riding with C—H = 0.95 Å for aryl-CH, C—H = 0.98 Å for CH3 groups and O—H = 0.84 Å for the hydroxy group. Isotropic displacement parameters for hydrogen atoms were constrained to Uiso(H)= 1.2Ueq(C) for aryl H-atoms and Uiso(H) = 1.5Ueq(C,O) for methyl and hydroxy groups.

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.
