A new macrocyclic ligand for Eu3 +, 24,30-diphenyl-8,19-(l,21:4,6:10,12:15,17-tetraetheno-8,9,19,20-tetrahydro-7AT,18^r-dibenzo[A,^][l,4,7,10,13,16]hexaazacyclooctadecine)diacetic acid (1), was synthesized and its fluorescence characteristics were examined, particularly to compare with 4,7-bis(chlorosulfophenyl)-l,10-phenanthroline-2,9-dicarboxylic acid (BCPDA) that has proved to be useful as a label in time-resolved fluoroimmunoassays. The complex of macrocycle 1 with Eu3+ was found to have a higher fluorescence intensity as well as a longer fluorescence lifetime than that of BCPDA.
