The results showed that PPC was a thermotropic liquid crystal and displayed the cholesteric banded texture. The reaction conditions had the distinct effects on the propoxy content and liquid crystal property of PPC, with the reaction temperature and content of propionyl chloride increased, the degree of substitution of propoxy increased at the beginning, then trended to steady. The transition temperature and range of liquid crystalline phase were changed with the DS of propoxy, as the DS of propoxy increased, the melt point decreased, and the liquid crystalline phase transition temperature range of PPC get wider.

结果表明，产物PPC具有明显的热致液晶性能，且呈现出胆甾型液晶的彩色条纹织构；反应条件对产物丙酰基含量和液晶性能有显著影响，随反应温度提高和丙酰氯用量增加，产物丙酰基的取代度先增大，后趋于稳定；其相转变温度和温域随丙酰基取代度改变而相应变化，随丙酰基的取代度增大，产物的熔点降低，液晶温度范围变宽。

Two new binuclear complexes, [TpCu(μ-1, 1-N3)2CuTp](1) and [Tp(superscript *)Co2CoTp(superscript *)](2) Tp=tri (pyrazolyl borate and Tp(superscript *)=3,5-dimethyltri borate, have been synthesized and characterized by IR, UV-vis, ESR, and CV. The crystal structures of both complexes have been determined by X-ray single crystal diffraction.
