  • Patent number: 7550071
    Abstract: Methods are described for the electrochemical assembly of organic molecules on silicon, or other conducting or semiconducting substrates, using iodonium salt precursors. Iodonium molecules do not assemble on conducting surfaces without a negative bias. Accordingly, the iodonium salts are preferred for patterning applications that rely on direct writing with negative bias. The stability of the iodonium molecule to acidic conditions allows them to be used with standard silicon processing. As a directed assembly process, the use of iodonium salts provides for small features while maintaining the ability to work on a surface and create structures on a wafer level. Therefore, the process is amenable for mass production. Furthermore, the assembled monolayer (or multilayer) is chemically robust, allowing for subsequent chemical manipulations and the introduction of various molecular functionalities for various chemical and biological applications.

  • Patent number: 7052593
    Abstract: The present invention provides an electrochemical method for producing diaryl iodonium compounds wherein application of an electric current to an electrochemical cell containing a reaction mixture composed of a solvent, an iodoaryl compound and an electrolyte forms an oxidizing agent in situ. In this first step, the oxidizing agent is subsequently converted into a stable oxidized iodoaryl intermediate, typically an iodosyl compound. The electric potential is removed and in a second step a target aryl compound is introduced to the reaction mixture to react with the oxidized iodoaryl intermediate to form a diaryl iodonium compound.

  • Patent number: 6419814
    Abstract: Organoiodonium salts, including certain novel symmetrical and unsymmetrical diaryliodonium;. polyiodonium and cyclic iodonium salts are synthesized by a significantly improved electrochemical coupling reaction which provides greater control and selectivity over the end product produced. Reaction mixtures comprising aryliodides and/or aromatic substrates are electrolyzed in novel reaction mediums comprising strong acid electrolyte, lower carboxylic acid, and preferably in the presence of acid anhydride in amounts >10 percent by-weight, and up to 50 percent by-weight or more, to provide a high degree of product selectivity, and at yields which can even be quantitative. The methods are conducted by introducing the electrolysis reaction mixture into an undivided electrochemical cell equipped with a cathode and preferably a conductive carbon anode.
