| 摘要: 以肉桂酸C9H8O2(HL)及其衍生物对位取代肉桂酸R-L(R=CH3,Cl,NO2,OCH3,OH)为配体,分别与Eu3 配位,得到系列Eu3 配合物。X-射线单晶解析结果表明:对甲基肉桂酸铕(1)和对氯肉桂酸铕(2)为一维高分子链,对硝基肉桂酸铕(3)为双核结构。通过FT-IR和UV-Vis光谱分析了配体在配位前后的变化。记录和解析了各配合物的荧光光谱,研究了对位取代基吸电子性和配位小分子对配合物发光性能的影响。 |

| Abstract: Europium complexes with cinnamic acid (HL) and its para-substitued derivates R-L (R=CH3, Cl, NO2, OCH3, OH) have been synthesized, and their crystal structures have been determined. The results of single-crystal X-Ray diffraction have shown that {[Eu2(CH3-L)6(DMF)(H2O)]·2DMF·H2O}n (1) and {[Eu2(Cl-L)6(DMF)(H2O)]·2DMF·H2O}n (2) are 1D chain coordination polymers while {[Eu2(NO2-L)6(DMF)(H2O)]·2DMF·H2O}2 (3) is binuclear structured. The complexes have been characterized by FT-IR, UV-Vis and photoluminescence (PL) spectroscopy. The influence of substituted groups' electron-withdrawing effect has been discussed. The effect of coordinated solvent molecular on complexes' luminescent properties has been investigated. CCDC:856461, 1; 856460, 2; 856462, 3. |
