摘      要：Nucleobase-metal coordination polymers(CPs)have been the target of much recent research owing their interesting properties and ease of *** nucleobases are nonfluorescent,and 2-aminopurine(2AP)is a strongly fluorescent analog of *** this work,we compared the CPs formed by adenine,2AP and adenosine with various *** Au3+produced CP nanoparticles with both adenine and *** products were similar in terms of size,suggesting that the position of the exocyclic amine is unimportant for coordination with *** 2AP is fluorescent,the dissolution of the nanoparticles in the presence of various chemicals including KCN,GSH,iodide,bromide and chloride,was studied and compared to fluorescent adenosine-Au *** appears that the 2AP CP was more robust than the adenosine one since even chloride can quench the fluorescence of the adenosine/Au ***,the adenine and 2AP nanoparticles exhibited weak oxidase-like activity for oxidation of TMB possibly by the Au3+exposed on the surface.
