摘　　要：A series of novel tripodal colorimetric anion sensors based on hydrazone CH=N--NH groups have been synthesized and their recognition behavior with anionic guests has been studied. In DMSO solutions, sensors 1 and 2 show colorimetric responses for F^-, H2PO4 and AcO^-, while in DMSO/H20 （9 ： 1, V/V） solutions, sensor 1 shows single selectivity for AcO^-. ^1H NMR titration confirms that the tripodal sensors could bind anions through the collaboration of three hydrazone groups and anions residing in the central cavity of the sensors.A series of novel tripodal colorimetric anion sensors based on hydrazone CH=N--NH groups have been synthesized and their recognition behavior with anionic guests has been studied.
