Abstract

In order to better understand the liquid crystalline behavior of recently synthesized metal hydroxamates, optical microscopy and differential scanning calorimetry have been employed. Analysis of their thermal stability and loss of mass by thermogravimetry and differential thermal analysis has been performed. The nematic mesophase can be observed in nearly all metal hydroxamates, with the exception of N-4-isopropoxyphenyl-4'-n-butoxycinnamohydroxamic acid complexes and iron hydroxamic acid complexes. Copper(II) hydroxamate complexes of N-4-n-butoxyphenyl-4'-n-butoxycinnamo hydroxamic acid and N-4-isoamyloxyphenyl-4'-n-butoxycinnamohydroxamic acid exhibit nematic as well as smectic behavior.

金属羟基酸盐的液晶行为
为了更好地了解最近合成的金属羟基酸盐的液晶行为,光学显微镜和差示扫描量热法已经被使用。用热重法和差热分析法对其热稳定性和质量损失进行了分析。除n- 4-异丙氧基苯基-4′-正丁氧基肉桂羟肟酸配合物和铁羟肟酸配合物外,几乎所有金属羟肟酸都存在向列相中间相。n- 4-正丁氧基苯基-4′-正丁氧基肉桂羟肟酸和n- 4-异淀粉基苯基-4′-正丁氧基肉桂羟肟酸的铜(II)羟酸配合物表现出向列性和近晶性。
