Synthesis and structure of 1,4-diazabutadiene liquid crystals

Article abstract of DOI:10.1080/10587250108025051

Nine 1,4-diazabutadiene compounds, Ar-N=C(R)-C(R)=N-Ar, R=H, Me; Ar= H_2n+1C_nO-C₆H₄, 2,4-(H₉C₄O)(Me)-C₆H₃ were synthesized and their liquid crystal properties were studied through thermal polarizing microscopy. The X-ray single crystal structure of compound 9 (Ar-N=C(H)-C(H)=N-Ar, Ar=2,4-(Me)(H₉C₄O)C₆H₃) was tested. It is a monoclinic crystal system, space group P2₁/C with the unit cell parameters: a=7.0703(3)A, b=8.674(4)A, c=18.3115(8)A, β =95.392(1)°. V=1114.57(9)A³, z=2, Dc=1.134 Mg/m³, R=0.0490,Rw=0.1237.
