A convenient synthesis and preliminary photophysical study of novel fluoroionophores: macrocyclic polyamines containing two dansylamidoethyl side arms

摘要

A series of novel fluorophores,consisting of macrocyclic polyamines containing two dansylamidoethyl side arms were synthesized as potential zinc (II) fluoroionophores by the reaction of the appropriate macrocyclic polyamines with N-dansylaziridine in acetonitrile at reflux temperature.Preliminary photophysical studies of ligand 3a,1,7-dmehtyl-4,10-bis(dansylamidoethyl)-1,4,7,10-tetraazacyclododecane,3j8,13-bis(dansylmidoethyl)-3-hydroxymethyl-1,3,10-trithia-8,13-diazacyclopentadecnae,and their complexes with Cu~(2+),Zn~(2+),Cd~(2+),and Hg~(2+) are described.
