Abstract
AbstractWe have synthesized thirteen novel metallomesogens based on dithiolene nickel complex showing π-acceptor properties: (o-C12OPhO)4DTNi (1), (m-C12OPhO)4DTNi (2), (p-C12OPhO)4DTNi (3), [o,m-(C12O)2PhO]4DTNi (4), [m,m′-(C12O)2PhO]4DTNi (5), [p,m-(CnO)2PhO]4DTNi (6: n = 10(a), 12(b), 14(c), 16(d)) and Cl-[p,m-(CnO)2PhO]4DTNi (7a–d). By using plarizing microscopic observations, differential scanning chalorimetry, and temperature-variable X-ray diffraction studies, the columnar liquid crystalline mesophases were established for the 6a–d and 7a–d derivatives. It was also revealed from the electrochemical measurements that each of the complexes of 1–7 showed good π-acceptor abilities. In particular, the derivatives, Cl-[p,m-(CnO)2PhO]4DTNi (7a–d), exhibit the most positive reduction potential from +0.08 to +0.07 V versus.

期刊介绍：
Established in 1966, Molecular Crystals and Liquid Crystals is a world-leading journal publishing original research papers in both an experimental and theoretical nature in three areas of specialization: liquid crystals, molecular crystals, and low-dimensional solids. These cover, but are not limited to:
Liquid Crystals:
-Electro- and magneto-optical phenomena; thermodynamics; phase transitions; structure; NMR and orientation-controlled spectroscopy; theory.
Molecular Crystals:
-Spectroscopy; energy and charge transfer; solid state reactions; photo and radiation effects
Low-dimensional Solids:
-Structure, electronic, magnetic, and optical properties; transport mechanisms
The journal publishes research papers, review papers, and book reviews. In all three areas, experimental manuscripts describing both preparation and properties will be considered. Papers that describe determination of crystal structure alone are not encouraged unless some solid state forces (hydrogen bonding, charge transfer, etc.) are playing a significant role and/or some solid state properties of the materials are measured.
