چکیده
Electron-withdrawing heterocyclic units are found in most organic optoelectronic materials. Benzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole) is an interesting new system, the chemical properties of which much less studied than other fused thiadiazoles. Cyano derivatives electron-accepting heterocycles known as potential components photoluminescent In this communication, benzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole)-4-carbonitrile was successfully obtained via cyanation 4-bromobenzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole) with copper(I) cyanide DMF. The structure newly synthesized compound established by means elemental analysis, high-resolution mass spectrometry, 1H and 13C NMR, IR spectroscopy.

3′,4′-Dimethoxybiphenyl-4-carbonitrile
The title compound, C(15)H(13)NO(2), was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the biphenyl rings is 40.96 (6)°. The meth-oxy groups are twisted slightly out of the plane of the benzene ring [C-C-C-C torsion angles = -3.61 (18) and 12.6 (2)°]. The packing of the molecules is stabilized by van der Waals inter-actions.
متن کامل4'-Octyloxybiphenyl-4-carbonitrile polymorph III.
The title compound, C21H25NO, is a member of a well known family of liquid crystals (4-oxy-4'-cyanobiphenyls, OCBs) and packs in lamellar-type bilayers in the solid state, through CN...H hydrogen bonds. This packing type is analogous to that found of other members of the n-OCB homologous series, viz. 7-OCB and 9-OCB.

In the title compound, C(16)H(13)IN(2), the benzene ring of the tetra-hydro-isoquinoline moiety makes a dihedral angle of 45.02 (9)° with the benzene ring of the 4-iodo-phenyl fragment. The N atom and the adjacent unsubstituted C atom of the tetra-hydro-isoquinoline unit are displaced by 0.294 (2) and 0.441 (3) Å, respectively, from the plane through the remaining eight C atoms. In the crystal,...
