title: The synthesis of novel fluorescent purine analogues modified by azacrown ether at C6.
abstract: The synthesis and fluorescence properties of novel purine analogues linked azacrown ether at C6 position were investigated. These new purine analogues could be prepared from a series of 6-chloropurines and showed selective and efficient signaling behaviors toward micromolar concentration of Ag(+) ion over other common metal ions in an aqueous environment.
