Abstract

Transition metal complexes of aliphatic triazole M(1)₃Cl ₂ (M: Fe, Co) (1: C₁₂OC₃Trz, M = Co(II), Fe(II)) gives heat-set gel-like networks in organic media. In this study, we investigated their interaction with liquid crystal molecules. When liquid crystal (JC-1041XX) was added to M(1)₃Cl₂ (M: Fe, Co) in CHCl₃at a weight ratio of 9:1, stable organogels were obtained. They show reversible spin transition (Fe^II) and coordination changes (Co^II), without dissolution of the gels. Apparently, nanofibrous assemblies of M(1)₃Cl₂ were stabilized by the interaction with liquid crystal molecules. Freeze-dried chloroform gels showed nematic liquid crystals as observed by polarized optical microscopy. The metal complexes in liquid crystals would provide a new research area in materials chemistry.
