摘　　要：合成并表征了含有苯环(3a^3d)和萘环(3e^3h)的两系列二茂铁查尔酮衍生物.这些化合物具有较好的紫外可见吸收性质.循环伏安实验中代表化合物3b与3f均展示可逆的单电子氧化还原进程,且萘环取代苯环对二茂铁的氧化还原性质未产生影响.与二茂铁相比,二茂铁查尔酮衍生物难失去电子,稳定性增加.热性质研究表明,两系列化合物均在250~260℃左右开始降解,对于同一系列化合物3a^3d或3e^3h,随着烷基链的增加,熔点都出现下降趋势.当分子刚性部分以苯环为主时,随着烷基链的加长,第一次升温中发生了不稳定的多晶相转变;当分子含有萘环时,分子熔点升高,此时延长烷基链对晶相的稳定性影响不大.这些研究为此类化合物在功能材料方面的应用提供一定的理论依据.Ferrocene-containing chalcone derivatives with benzene rings （3a-3d） or naphthalene rings （3e-3h） were synthesized and characterized. These compounds exhibited good UV-vis absorption properties. The cyclic voltammogram investigations revealed that redox-active ferrocenyl groups of 3b and 3f exhibited one-electron transfer processes and naphthalene rings instead of benzene rings had little or no effect on the formal redox potential of ferrocenel As compared to the ferrocene standard, it was difficult to lost electron for ferrocene-containing chalcone derivatives indicating their high stability. Their thermal behaviors indicated that these compounds started to decompose at about 250-260 ℃, and the melting points decreased with lengthening terminal alkyl chains. When the rigid phic phase transitions with lengthening terminal alkyl chains core of molecular were mostly benzene rings, crystal polymor, was observed in the first heating cycle; whereas the melting points increased when the rigid core of molecular contained naphthalene rings, and lengthening terminal alkyl chains had little effect on the crystal phase stability. The research is supposed to provide some theoretical basis for this kind of compound using in function materials.
