Study Of The Synthesis Of Ruthenium Complexes And It's Self-assembly Application

Electrochemiluminescence (also called electrogenerated chemiluminescence and abbreviated ECL) is the process whereby species generated at electrodes undergo high-energy electron-transfer reactions to form excited states that emit light. Electrochemiluminescence (ECL) of tris(2,2'-bipyridine)Ruthenium(II) [Ru(bpy)32+] has been attracting much attention in biochemical analysis, clinical diagnosis and scientific research because of its high sensitivity, wide dynamic range, stability and simplicity etc.10C,12C and 14C, three bimetallic ruthenium complexes covalently linked through different length carbon chain have been synthesized. Their ECL property have been studied by using of tripropylamine (TPrA) and 2-(dibutylamino) ethanol (DBAE) as the coreactant, the results demonstrate that the best length of carbon chain is ten.The research of the interaction of metal complexes and DNA is a theoretical and practical work, a new complexes RuG which can be used for DNA identification was synthesized, the fluorescence can be greatly enhanced after binding with DNA, which has certain advantages in comparison with the traditional RuDPPZ complex. At the same time, we used IOC,12C and 14C bimetallic ruthenium complexes to assemble with SMNTs to detect DNA, proposed the idea of using the self-assembly supramolecue for molecular recognition.The recombination of the CB[8] self-assembly supramolecule was first utilized to detect paraquat, proposed a novel fluorescent method to detect paraquat.
