Effect of Aggregation of Acridine Orange on the Luminescent Characteristics of Its Composites with a Zinc-Containing Coordination Polymer

It was shown that the luminescent characteristics of the composites formed by the zinc-containing coordination polymer {[Zn(L)(NDC)]·0.5H 2 O} n (L = cyclam, NDC 2– = 2,6-naphthalenedicarboxylate) with acridine orange depends on the ratio of the amounts of aggregated and isolated molecules of the dye, which in turn depends on the conditions under which the composites are produced. In all cases energy is transferred from the coordinated polymer to the dye, leading to bimodal luminescence in the composites.
