Source of material
The title compound was synthesized according to procedures described in the literature for an analogous compound [4]. 2,5-Diethoxy-1,4-bis(triphenylphosphonium)benzene dichloride (1.18 g, 1.5 mmol) and isonicotinaldehyde (0.43 g, 4 mmol), fresh t-BuOK (1.12 g, 10 mmol) were crashed together with pestle and mortar at room temperature for 0.5 h. Separation of cis- and trans-isomers was accomplished by radial chromatography technique using a Chromatotron apparatus and petroleum/ethyl acetate (20:1) as the eluting solvent. Single crystals of the cis-isomers were grown slowly by evaporating solutions in DMF solvents. m/z 373.21 [M + H]+.1H-NMR (CDCl3, 400 MHz, ppm): δ 8.48 (d, J = 4.8 Hz, 4 H), 7.63 (d, J = 12 Hz, 2H), 7.10 (d, J = 2.3 Hz, 4H), 7.05 (s, 2H), 6.92 (d, J = 12 Hz, 2H), 4.07 (q, J = 7.0 Hz, 4H), 1.39 (t, J = 7.0 Hz, 6H).
Experimental details
All H-atoms were placed in calculated positions and treated as riding on their parent atoms: C—H = 0.93–0.97 Å, with Uiso(H) = 1.2 or 1.5 Ueq(parent C-atom).
Discussion
The oligo(phenylene vinylene) derivatives (OPVs) are important materials in the fields of nonlinear optics [5, 6] , solid state opto-electronics [7] and molecular devices [8]. But in all kinds of OPVs, the presence of π-extended bridges are easy to form cis/trans-vinylene units and photochemical isomerized compounds. Thus, efforts have been made in the investigation of relationships that exist between the cis and trans configuration in one/two-photon luminescence properties.
The asymmetric unit contains one half of a title molecule, located around an inversion center. The crystal structure analysis reveals that the C = C double bonds adopt all cis configuration (cf. the figure). The bond length of C = C double bond is 1.3402(16) Å which is slightly longer than those in the related compound [4]. The torsion angles between the double bond and two adjacent phenyl rings are 131.72(10)° and 131.22(10)°. The dihedral angles between terminal pyridinyl moieties and the central aren unit are 42.3°. The configuration affords steric hindrance that prevents π-stacking in the solid state and thus promotes luminescence properties.
