合成并表征了一系列单取代及1,1’-双取代1,2,3-三唑基二茂铁衍生物.与单取代二茂铁衍生物相比,1,1’-双取代二茂铁衍生物具有较大的摩尔吸光系数.荧光光谱中,烷氧链的增加和氯原子的引入均使化合物的荧光强度减弱,量子产率降低.循环伏安实验中,代表化合物展示准可逆的单电子氧化还原进程,并且1,1’-双取代三唑基二茂铁衍生物的半波氧化还原电位较单取代化合物向阳极移动150 m V左右,表明前者难于发生失电子氧化反应.热性质研究表明,这些化合物的降解温度在285~305℃之间.含有单烷氧链的单取代二茂铁衍生物熔点较高,在加热过程中未熔解而是直接发生了降解反应;含有多烷氧链的化合物熔点降低,在加热和冷却过程中有的发生了单晶相的熔解和凝固过程,有的发生了多晶相到液相的转变.
A series of monosubstituted and 1,1’-disubstituted 1,2,3-triazolyl ferrocene derivatives were synthesized and characterized.Compared with monosubstituted ferrocene derivatives, 1,1’-disubstituted bis Ferrocene derivatives have a larger molar extinction coefficient.In the fluorescence spectrum, the increase of alkoxy chain and the introduction of chlorine atoms make the fluorescence intensity of the compound weakened, the quantum yield decreases.In cyclic voltammetry, the representative compounds exhibit quasi-reversible The half-wave redox potential of the 1,1’-disubstituted triazolylferrocene derivatives is about 150 mV more than that of the monosubstituted compounds toward the anode, indicating that the former is less prone to electron-deficient oxidation. The thermal properties of these compounds show that the degradation temperature of these compounds is between 285 and 305 ° C. Mono-substituted ferrocene derivatives containing monoalkoxy chains have a higher melting point and do not melt but undergo a direct degradation reaction during the heating process. Polyoxyalkylene compounds have a lower melting point. During the heating and cooling process, the melting and solidification of the single crystal phase occurs, and some transition from polycrystalline phase to liquid phase occurs.
