Abstract White-light emitting lanthanide(iii) metal-organic coordination polymers (LMOCPs) were prepared via a green synthesis method performed in pure aqueous solution at room temperature without using toxic solvent and reagents. This kind of LMOCP, denoted as adenosine monophosphate (AMP)/Ln-CIP, was composed of Ln3+ {Ln = Tb (1), Eu (2), and Gd (3)}, hydrosoluble biomolecule of AMP, and nonpoisonous antenna ligand of CIP (ciprofloxacin). The complex of Tb(1), Eu(2), and Gd(3) in AMP/Ln-CIP emits strong green, red, and blue light, respectively. With careful adjustment of the doping mole ratio of the three lanthanide ions {Ln = Tb:Eu:Gd = 0.1:0.9:99.0} in one framework, white light-emission can indeed be achieved. AMP/Ln-CIP is network-structural and amorphous by transmission electron microscope and X-ray diffraction analysis. The fluorescence lifetime and quantum yield of AMP/Ln-CIP are 4.36 ms and 36.5%, respectively.

基于核苷酸的镧系配位聚合物绿色合成用于可调白光发射

摘要 通过绿色合成方法在室温下在纯水溶液中不使用有毒溶剂和试剂制备了发白光的镧系元素（iii）金属有机配位聚合物（LMOCPs）。这种LMOCP，表示为腺苷一磷酸（AMP）/Ln-CIP，由Ln3+{Ln=Tb（1）、Eu（2）和Gd（3）}、AMP的水溶性生物分子和无毒天线配体组成CIP（环丙沙星）。AMP/Ln-CIP 中 Tb(1)、Eu(2) 和 Gd(3) 的复合物分别发出强烈的绿色、红色和蓝色光。通过在一个框架中仔细调整三种镧系元素离子的掺杂摩尔比 {Ln = Tb:Eu:Gd = 0.1:0.9:99.0}，确实可以实现白光发射。通过透射电子显微镜和 X 射线衍射分析，AMP/Ln-CIP 是网络结构和无定形的。
