Bis-(N-R,4-decyloxybenzoyloxysalicylideneaminato)oxovanadium(IV) complexes (where R = n-CmH2m+1 and m= 1,5,10 or R =–C6H4–O–CmH2m+1 and m= 1,2,5,10) showed a paramagneticnematic mesophase (except for R = Me), and some complexes also showed smectic phases; the low viscosity of the mesophase allows the easy orientation of the molecules in a magneticfield, the orientation remaining in the state solid.
双(N -R,4-癸氧基苯甲酰氧基水杨酰亚氨酰氨基)氧钒(IV)络合物(其中R = nC m H 2 m +1和m = 1,5,10或R = –C 6 H 4 –O–C m H 2 m +1和m = 1,2,5,10)表现为顺磁性向列中间相(R = Me除外),某些配合物也表现为近晶相。中间相的低粘度使分子在磁场中易于定向,该定向保持为固态。
