Synthesis and Properties of 2-Bromo-7-(1,4,7,10-tetraoxa-13-azacyclopentadec-13-yl)-2,4,6-cycloheptatrien-1-one
摘要:
2-Bromo-7-(1,4,7,10-tetraoxa-13-azacyclopentadec-13-yl)tropone (1) was found to display unique absorption spectral changes in the presence of guest cations. The compositions of I with guest salts were 1: 1 for Mg(SCN)(2), Ca(SCN)(2), and Ba(SCN)(2), 1:2 for CdI(2) and 1:1.5 for Zn(SCN)(2), respectively. Azacrown ether (1) could be used as a carrier for transport of Hg(2+) through a chloroform liquid membrane.
