Self Assembled Monolayer (SAM): Applications

The conjugate organic SAMs can provide all the ingredients to create new hybrid materials with novel functionalities out of the scope of traditional solid state devices, and this class of molecules contain very interesting electronic and magnetic properties, such as the existence of Giant magneto resistance (GMR) in phenyledithiolate molecules between nickel contacts1, and electron transport by charge injections through different molecular orbital MOs2. In this presentation I will show the building block Method using dithiols-molecules (such as BDMT) and metal ions to create new hybrid materials.

Synthesis, Characterization and Application of Mesoporous Transition-Metal Oxides

Due to their large surface areas and pore volumes, tunable and uniform mesopore sizes, mesoporous silicas have attracted much interest and studied extensively. However, the lack of electronic conductivity of silica has limited possible application ranges. Therefore, for practical applications such as electrochemical sensors, electroluminescent films, and photovoltaic cells, mesoporous transition-metal oxides with electronic conductivity is required. However, preparation of mesoporous metal oxides using organic surfactants as soft-templates often resulted in the collapse of mesoporous structures due to the crystallization of pore walls during calcination process. I overcame this problem by using a thermally-robust copolymer as a soft-template and succeeded in obtaining ordered mesoporous metal oxides thin films (TiO2, SnO2, and Nb2O5). In this seminar, I will introduce these two topics.

  1. Synthesis of mesoporous SnO2 thin films and antimony doping toward transparent conductive electrodes.
  2. Synthesis of mesoporous TiO2 thin films and its application to polymer/inorganic hybrid solar cells.
