Abstract

A novel pentaazadentate bismacrocycle was synthesized through an improved procedure of 1:1 Schiff base condensation of diformyltripyrrane with 3,4,3′,4′-tetraamino-biphenyl hydrochloride using Pb2+ as template ion, in which the condensed byproduct water was removed efficiently to make the yield over 90%. Then the bismacrocycle legend reacted with cadmium chloride to yield the title metal complex with molecular weight being 1200.4 by TOF MS and the λmax being 766 nm.
