Aroylhydrazinatonickel(II) and copper(II) complexes; a new class of metallomesogens

Abstract

A series of aroylhydrazinato-nickel(II) and -copper(II) complexes have been synthesised in high yield and shown to form a new class of metallomesogens, which form smectic C and nematic phases; the nickel(II) complexes were found to be highly stable even in the isotropic phase, which contrasted with the rapid decomposition of the copper(II) complexes soon after entering the liquid crystalline phase.
