A New Series of Kinked Liquid Crystals: 2-(6-Alkoxynaphthalen-2-yl)-6-methoxyquinolines

A new series of 2-(6-alkoxynaphthalen-2-yl)-6-methoxyquinolines (nO-NpQOMe, n = 3-8) liquid crystal compounds, a linear molecular structure with two kinks, were synthesized using a short two-step reaction with overall yields between 43% and 58%. Spectral analyses were in accord with the expected structures. Thermotropic behavior of these liquid crystal compounds were investigated using polarize...

Synthesis and Thermotropic Studies of Two Novel Series of Kinked Liquid Crystals: 2-(4′-Alkoxybiphen-4-yl)-6-methylquinolines and 2-(6-Alkoxynaphthalen-2-yl)-6-methylquinolines

Two novel homologous series of kinked (Z-shaped) liquid crystalline compounds were synthesized using a short two-step reaction. Yields of 30%-40% and 51%-57% were obtained for 2-(4'-alkoxybiphen-4-yl)-6-methylquinolines (nO-PPQMe, n = 3-8) and 2-(6-alkoxynaphthalen-2-yl)-6-methylquinolines (iO-NpQMe, i = 3-7), respectively. Spectral analyses agreed with the expected structures. The thermotropic...

1-[6-(6-Acetyl­pyridin-2-yl)pyridin-2-yl]ethanone

In the title compound, C(14)H(12)N(2)O(2), the asymmetric unit comprises one half-mol-ecule with an inversion center between the pyridine rings. The rings are trans coplanar with the acetyl groups deviating slightly from the mean planes, making a dihedral angle of 4.63 (4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, forming a supra-molecular sheet paral...

2-(6-Bromopyridin-2-yl)-6-methyl-[1,3,6,2]dioxazaborocane, a new stable (pyridin-2-yl)boronic acid derivative.

The crystal structure of the ®rst reported non-substituted N-methyldioxazaborocane con®rms that the presence of a methyl group attached to the N atom introduces an N!B bond length that is longer than that in a simple dioxazaborocane ring. The presence of more N atoms in the vicinity of the B atom in the title compound [systematic name: 6a-(6bromopyridin-2-yl)-3a-methyl-2,3,4,5-tetrahydro-1,6-di...

2-Meth­oxy-6-(6-methyl-1H-benzimid­azol-2-yl)phenol

In the title mol-ecule, C(15)H(14)N(2)O(2), the substituted benzene ring forms a dihedral angle of 4.15 (1)° with the benzimidazole ring system. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the solid state, mol-ecules are linked into chains along the [001] via inter-molecular bifurcated N-H⋯(O,O) hydrogen bonds, which generate R(1) (2)(5) ring motifs. The crystal pack...
