Spin crossover characteristics of nanofibrous FeII-1,2,4-triazole complexes in liquid crystals

Abstract

A lipophilic linear Fe(II) complex is dispersed as nanofibers in nematic liquid crystals and displays spin-crossover at temperatures higher than those observed for the bulk crystalline state; thermal bistability is also induced in the liquid crystal environment, reflecting increased ligand field splitting energy and enhanced cooperativity by liquid crystals.
