Pyridine-contained α-Cyanostilbenzene Schiff Base: Preparation, Crystal Structure and Photoluminescence
摘要:
A novel pyridine-contained α-cyanostilbenzene Schiff base, (Z)-3-(4-butoxyphenyl)-2-(4-((E)-pyridin-2-yl-methyleneamino)phenyl)acrylonitrile (L), has been synthesized and characterized by 1H NMR, 13C NMR, FT-IR spectra and single-crystal X-ray diffraction. Single-crystal data show that compound L belongs to the triclinic system, space group P1, with a=8.759(4), b=10.779(4), c=12.594(5)Å, α=65.873(4), β=88.332(5), γ=73.800(5)°, Mr=381.46, V=1037.2(7)Å3, Z=2, Dc=1.221 g/cm-3, μ=0.076 mm-1, F(000)=404, Rint=0.0311, R (I>2σ(I))=0.0484, wR (I>2σ(I))=0.1544, R (all data)=0.0484, wR (all data)=0.1692, completeness to theta=25.000 being 99.0% and GOF=1.179. There are two kinds of intermolecular hydrogen bonds and one kind of C-H…π weak interaction between adjacent molecules. Compound L can be used as a candidate for desirable devices with high performance due to its good thermal stability and excellent optical performance.
