开发了一种绿色调制协同法合成分层结构的稀土金属有机骨架材料Eu（BTC）（H2 O）6，解决了传统合成方法中使用大量的、有毒有机溶剂的难题，用乙醇和碱性添加剂代替传统的有毒溶剂DMF。首先用乙醇将有机配体溶解，然后加入碱性添加剂使有机配体去质子化，从而使其与金属中心Eu3＋成功配位，通过添加剂的-COO －与BTC配体的-COO －竞争与Eu3＋的配位合成形貌各异的Eu（BTC）（H2 O）6晶体。绿色调制协同法，利用碱性物质乙酸钠和甲酸钠作为调制剂成功制备了多种形貌的Eu（BTC）（H2 O）6，包括十字花状晶体、小麦状晶体、麻花状晶体、花状晶体、稻草捆状晶体和杂乱的稻草捆状晶体。这些多形貌的晶体利用粉末X射线衍射、扫描电子显微镜、红外光谱和热重等表征确定了晶体的结构、形貌及化学组成。

This paper developed a green coordination modulation method to synthesize hierarchical lanthanide coordina-tion polymers Eu(BTC)(H2 O)6 .Ethanol and alkaline additives instead of conventional toxic solvents DMF were used as organic solvent and modulator respectively.The role of alkaline additives (sodium acetate and sodium formate)in tailoring the crystal morphology is related to its basicity (increase nucleation rate)and capping groups (COO -)(pre-vent crystallites from growing).Various morphologies of Eu(BTC)(H2 O)6 crystals were obtained,including cross-flowerlike crystals,wheat-like crystals,twist-like crystals,flowerlike crystals,straw-sheaflike crystals and unorganized straw-sheaflike crystals.These crystals were characterized by X-ray diffraction,SEM,FT-IR and TGA to determine their structure,morphology and chemical composition.
