摘　　要：2-Ureido-4[1H]-pyrimidinone quadruple hydrogen-bonded assembly 1,1 containing N,N-dimethylaminophenyl moiety exhibits a sensitive response to fluoride anion and lead cation. Spectroscopic studies reveal that the presence of small amount of fluoride anions and lead cations can easily disassemble and intercalate 2-ureido- 4[ 1H]-pyri mi di none hydrogen-bonded supramolecular architectures.2-Ureido-4[1H]-pyrimidinone quadruple hydrogen-bonded assembly 1,1 containing N,N-dimethylaminophenyl moiety exhibits a sensitive response to fluoride anion and lead cation.
