Linear conjugated structure of the molecule leads to build molecular electronics devices important component unit having a certain rigidity of the ferrocene acetylenic compound has good electrochemical properties , by appropriate functional modifications can be used as molecular wires . In this thesis the synthesis, characterization and photovoltaic performance in several ferrocene acetylene compounds some of the work , the main contents are as follows: acylation , Friedel - diazotization , and Sonogashira coupling reactions and gradually coupling growth method, design and synthesis of the following three types of functional ferrocene acetylenic molecular wires compound : (1) end of as acetyl mercapto group or a methylthio group , and the other end the ferrocene ethynyl ferrocene acetylene thiophenol (2) one end of the derivatives; ferrocenyl acetylene group at one end is amino ferrocene ethynyl aniline derivatives ; (3) one end of ferrocene acetylene group at one end for benzoic ferrocene acetylene benzoic acid derivatives . Second, the above compound characterization of nuclear magnetic resonance spectroscopy, infrared spectroscopy and mass spectrometry to determine its structure . The three new ferrocene acetylene compounds optical and electrochemical properties of spectroscopy and electrochemical studies of the target compounds . Three kinds of functional ferrocene acetylenic molecular wires UV and fluorescence spectrometry of the compound : The results showed that these compounds in an organic solvent , has good UV absorption , fluorescence properties are generally poor ; cyclic voltammetry experiments showed that these compounds in acetonitrile - lithium perchlorate solution has a reversible redox peaks , corresponding to the Fc / Fc peak ; modified gold electrodes through molecular wires assembled with the sulfatide base and methylthio compounds of biological molecules the catalytic oxidation study found : the compound molecular wires with the sulfatide base and methylthio compounds rutin have good electro-catalytic oxidation ; complexes prepared pot legal system through research ferrocene acetylene amines and graphene modified the electrode electrocatalytic oxidation of small biomolecules : the complex electrocatalytic activity of dopamine .
