The self-assembly of a thymine nucleotide-calixarene hybrid ( 1) in CDCl3 as a solvent was investigated. FT-IR, ESI-MS, 1 H and DOSY-NMR spectra evidenced that compound 1 ( ammonium or sodium salt) self-assembles in a triangular trimeric supramolecule by thymine-thymine hydrogen bonding. The saline form is crucial for the arrangement in the cyclic trimer as the protonation of the nucleotide phosphate groups leads the assembly toward a dimeric species. (c) 2007 Elsevier Ltd.

Abstract
The self-assembly of a thymine nucleotide-calixarene hybrid ( 1) in CDCl3 as a solvent was investigated. FT-IR, ESI-MS, 1 H and DOSY-NMR spectra evidenced that compound 1 ( ammonium or sodium salt) self-assembles in a triangular trimeric supramolecule by thymine-thymine hydrogen bonding. The saline form is crucial for the arrangement in the cyclic trimer as the protonation of the nucleotide phosphate groups leads the assembly toward a dimeric species. (c) 2007 Elsevier Ltd.
