Source of material

The title compound was synthesized by solid-phase Wittig reaction. 2,5-Diethoxy-1,4-bis(triphenylphosphonium)benzene dichloride (1.18 g, 1.5 mmol) and quinoline-2-carbaldehyde (0.63 g, 4 mmol), fresh t-BuOK (1.12 g, 10 mmol) were crashed together with a pestle and mortar at room temperature for 0.5 h. Then, the product was purified silicagel column chromatography (8:1 v/v petroleum/ethyl acetate) in 52% yield as yellow solid. Single crystals of the title compound suitable for X-ray analysis were obtained from CH3CN solvent.

Experimental details

All H-atoms were placed in calculated positions and treated as riding: C—H = 0.93–0.97 Å, with Uiso(H) = 1.2 or 1.5 Ueq(parent C-atom).

Discussion

The oligo(phenylene vinylene) and its derivatives (OPVs) are one kind of highly conjugated linear molecules, attracting increasing interest in the fields of nonliear optic [1], solid state opto-electronics [2] and molecular devices [3]. A large number of OPVs with large two-photon absorption sections (nonliear optical properties) were synthesized and investigated by changing the donor/acceptor(D/A) strength, conjugation length [4], for their potential applications in two-photon fluorescence imaging, optical power limiting, two-photon up-conversion lasing, three-dimensional optical data storage, 3D microfabrication, and photodynamic therapy [5]. Some of OPVs's single crystal structures are reported to get an insight into packing of the molecules and to explain the mechanisms of luminescence phenomena [6–8]. Here, a quinoline-terminated OPV has been synthesized and its crystal structure is reported. The crystal structure reveals that the C = C double bonds adopt an all trans-conformation with the bond length 1.320(2), 1.323(2) Å. The dihedral angles between terminated quinoline rings and benzene ring are 6.3 and 9.9°, respectivelly. So the backbone is nearly coplanar. In the crystal structure intermolecular π−π interactions play a major role in the molecular packing. With a contact distance of 3.32 Å they connect molecules forming a ladder-like structure, which are further stacked into a 3D structure based on weak C—H⋯π interactions and C—H⋯N hydrogen bonds.
