Abstract
Reaction of diethylenetriamine with 2-nitrobenzenesulfonyl chloride leads t o an activated and protected compound that could be cyclized to N-protected aza-macrocycle. After a smooth deprotection step, the macrocycle was alkyl ated with chloroacetic acid leading to the pyridine containing triaza-macro cycle 1 in good yield. The luminescence properties of its Eu3+ complex were examined in aqueous solution. (C) 2000 Elsevier Science Ltd. All rights re served.
