  • Patent number: 9051401
    Abstract: A synthesis of a new pyrazole-containing monomer by means of an easily implemented two-step process. This monomer can be electropolymerized to yield a stable n-doping polymer that may easily be electrochemically characterized. It is demonstrated that the electrochemical behavior of the polymer films produced is dependent upon the conditions applied during electrodeposition. Films deposited by cycling only at relatively positive potentials (0 to 2000 mV) show less intense n-doping responses than those films obtained by scanning the applied potential throughout a wider range (?2000 mV to 2000 mV).

  • Patent number: 5810989
    Abstract: A method of photoelectro-synthesizing probe arrays including the steps of providing a photoconductive layer of material having a layer of electrically conductive material on a first surface thereof and a solution of a plurality of a first oligonucleotide modified monomer positioned in electrical contact with an opposing second surface thereof such that a potential is connected therebetween. A beam of light is directed through a portion of the photoconductive layer of material to complete an electrical circuit between the layer of electrically conductive material and the solution through the portion of the photoconductive layer, whereby the monomers in the solution are electropolymerized on a surface area which is coupled into the electrical circuit by the beam of light.

  • Patent number: 5527434
    Abstract: Provided is a method for preparing a conductive polymer which is highly transparent to visible light in at least one of its conductive and non-conductive states. A solution containing a monomer component and an electrolyte is introduced into an electrochemical cell and subjected to polymerization by cyclic voltammetry. The solution is maintained at a temperature within a range of from 0.degree. to -40.degree. C. inclusive. Prior to the polymerization, cyclic voltammetry is firstly performed at a potential below that at which anodic or cathodic polymerization may take place, anodic and cathodic limits (A) and (B) being held at respective values. A trace of current/voltage is monitored until the trace becomes stable, and thereafter the value of the limit (B) is progressively increased until the said value reaches a critical potential having a magnitude at which anodic or cathodic polymerization is initiated.
