摘要: Abstract A series of novel fluorophores, consisting macrocyclic polyamines containing two dansylamidoethyl side arms were synthesized as potential zinc (II) fluoroionophores by the reaction appropriate with N-dansylaziridine in acetonitrile at reflux temperature. Preliminary photophysical studies ligand 3a, 1,7-dimethyl-4,10-bis(dansylamidoethyl)-1,4,7,10-tetraazacyclododecane, 3j, 8,13-bis(dansylamidoethyl)-3-hydroxymethyl-1,3,10-trithia-8,13-diazacyclopentadecane, and their complexes Cu2+, Zn2+, Cd2+, Hg2+ are described.
