摘要
Liquid-crystalline mono-and binuclear complexes of Fe(III) based on pentadentate Schiff’s base, N,N′-bis(2-hydroxy-4-octadecyloxybenzyliden)-1,7-diamino-4-azaheptane, have been prepared for the first time. The effects of counterions of the binuclear complexes and of the monodentate ligand in the mononuclear complexes on formation of the mesophase as well as phase transitions temperatures and the range of the mesophase existence have been demonstrated. EPR studies have revealed the possibility of spin-crossover properties of the complexes.
