Abstract: A novelty rhodamine B based chemosensor containing 2-amino-7-methyl-1,8-naphthyridine moiety was designed and synthesized for colorimetric and fluorescent response on corresponding nucleoside polyphosphates through multi-hydrogen bond interaction in aqueous solution. The supramolecular recognition between the RBS and Cytidine-5'-diphosphate disodium hydrate (CDP) was investigated carefully: H-1 nuclear magnetic resonance confirmed that the formation of multi-hydrogen bonds between naphthyridine moiety and the nucleoside base group could untie the spiro structure of RBS, and the ESI-MS spectra proved the formation of the 1:1 complexation species between RBS and CDP. The strong emission response of the RBS toward COP and Adenosine-5'-triphosphate disodium trihydrate (ATP) ensures its application in living cells imaging. (C) 2013 Elsevier Ltd. All rights reserved.
