Synthesis And Spectroscopic Properties Of Bimetallic Ruthenium And Gold Complexes

With the continuous development of solid technology, the operation speed ofcomputer chips are getting smaller and faster and the functionality is getting stronger.However, the existing processing technology will soon not meet miniaturization ofdevices, the computer chip may achieved the limitation of physical size, Comparedwith conventional solid state electronics, molecular electronics has a strong advantage,just expected to solve these problems. Therefore, we hope atom or molecule canmanufacture electronic devices that molecular electronic devices. In recent years,"molecular electronic devices" have become a crossover study in chemistry, materialsscience and hot topics at the forefront of the international field. Classified by function,the switch elements can be divided into molecular devices, molecular memory,molecular rectifier FET molecules, molecular thyratron, molecular wires andmolecular motors. Which is the bridge between molecular wires molecularcomponents and external relations, effective molecular wires is the key element toachieve molecular electronic devices.1. In order to study the effects of lithium metal ions on the electrochemicalbehavior of vinyl compounds,we synthesized three types of compounds[RuCl(CO)(PMe3)3]2(μ-CH=CH Ar CH=CH)[Ar=C6H2(OCH3)2-2,3(1a),C6H2(OCH2CH2OCH3)2-2,3(1b), C6H2(OCH2CH2OCH2CH2OCH3)2-2,3(1c)]; Thestructures of these compounds were confirmed by elemental analysis, NMR,electrochemical spectroscopy and X-ray diffraction were used.The opticalproperties indicate that the complexes are a class of electrochemical sensor that canidentifying a lithium ion, in particular bimetallic complexes1c. Now,it is the firsttime through the bimetallic ruthenium conjugated molecular wires identifing thelithium ions,these studies provides a theoretical and experimental guidance for thedesign of a new mixed potential at the electrochemical sensor system application.2. In order to study the optical properties of bimetallic gold complexes ofacetylene and the impact of lithium ions, the synthesis of acetylene ten goldcomplexes [Au(PPh3)]2(C≡C-Ar-C≡C)[Ar=C6H2(OCH3)2-2,5(2a), C6H2(OC4H9)2-2,5(2b), C6H2(OC6H13)2-2,5(2c), C6H2(OCH2CH2OCH3)2-2,5(2g),C6H2(OCH2CH2OCH2CH2OCH3)2-2,5(2h), C6H2(OCH3)2-2,3(2d),C6H2(OC4H9)2-2,3(2e), C6H2(OC6H13)2-2,3(2f), C6H2(OCH2CH2OCH3)2-2,3(2i),C6H2(OCH2CH2OCH2CH2OCH3)2-2,5(2j), the spectra studies shows that thecomplexes are worse to the bimetallic ruthenium-conjugated molecular wires inlithium-ion response, this may because the weak interactions of lithium ion withcomplexes that can cause the spectral response.
