摘　　要：设计合成了一种新型腙类阴离子受体1。利用紫外-可见吸收光谱,荧光光谱考察了其与Ac O-,H2PO4-,Cl-,Br-,I-和F-几种阴离子之间的作用。当加入F-时,导致紫外光谱的可见光区明显变化(大约115nm红移),同时伴随着浅黄色变为蓝紫色的"裸眼"颜色变化。而加入其他离子后溶液颜色几乎没有发生颜色。据此建立了裸眼比色法检测F-的方法。A new hydrazone anion receptor 1,was designed and synthesized. The binding properties of the receptor with anions such as Ac O-,H2PO4-,F-,Cl-,Br-and I-were investigated by UV-Vis and fluorescent titrations. Upon addition of F-,results in a noteworthy change in the visible region of spectrum（ approximately 115 nm red shift）,accompanied by visible color changes from light yellow to blue purple. However,no obvious color changes were observed on addition of the other anions tested. Thus colorimetric assay for F-was developed.
