Electrosynthesis and Characterization of Semiconducting Molecular Materials in the Electrochemical Module of the Atomic Force Microscope

摘要: The search of new materials for electronics and optoelectronics applications has been the subject considerable research effort. Early on, inorganic received most attention in this regard, whereas organic organometallic derivatives were a state relative neglect. Recently, however, these last have generated an increasing interest, as some them may behave conductors or semiconductors could potentially be used diodes, solar cells, transistors electronic switches, among other devices. A common technique preparing is electrocrystallization, which based on formation radical ions by electrochemical oxidation reduction, simultaneous crystallization derived salt with counter-ion support electrolyte. This process normally carried out electrosynthesis conventional cells. An exciting alternative method uses module atomic force microscope (AFM). use AFM proposed more efficient way to generate molecular materials, it permits thin-film synthesis monitored manipulated before characterization. several advantages when compared traditional method. One fact that cyclical voltammetry studies can performed while material being synthesized determine reduction potentials relevant species. faster another advantage using module, requires only about three hours process, between one week two months. Another AFM-generated are directly deposited form, those obtained from cell’s anode require additional evaporation produce thin film. analysis samples made conducting, insulating semiconducting provides good topographic contrast lateral resolution imaging surfaces. In work, we make comparative study synthesizing characterizing module.
