一个手性三脚架配体被证明可以形成一系列的镧系元素配合物，表现出多个阴离子传感的配置文件，其中纳入了荧光喹啉和立体控制的取代基在一个四齿骨架。这主要是得到1：2（镧系阳离子/配体）配合物与镧系三氟甲磺酸盐，但1：1配合物与镧系硝酸盐。由于外部客体阴离子的加入动态地改变了优选的化学计量比，手性镧系元素配合物表现出阴离子响应的荧光，发光和圆二色光谱特性作为多个阴离子传感探针。(C)2009爱思唯尔有限公司保留所有权利。
A chiral tripodal ligand was demonstrated to form a series of lanthanide complexes exhibiting multiple anion-sensing profiles, which incorporated a fluorescent quinoline and a stereo-controlled substituent in a tetradentate skeleton. This mainly gave 1:2 (lanthanide cation/ligand) complexes with lanthanide triflates but 1:1 complexes with lanthanide nitrates. Since addition of external guest anion dynamically changed the preferred stoichiometry, the chiral lanthanide complexes exhibited anion-responsive fluorescence, luminescence, and circular dichroism spectral characteristics as multiple anion-sensing probes.
