Abstract
Naphthalene-naphthalene, anthracene-anthracene, and naphthalene-anthracene assemblies 1.1, 2.2, and 1.2 linked by 2-ureido-4 {1H}-pyrimidinone binding module were synthesized. Fluorescence quenching and lifetime measurements demonstrate that the inner-assembly sin let energy transfer from naphthalene to anthracene in 1.2 occurs with the efficiency of ca. 89% and rate constant of ca. 9.8 x 10(8) s(-1). Foster energy transfer mechanism operates in this energy transfer process. (C) 2004 Elsevier Ltd. All rights reserved.
