  • Publication number: 20100144083
    Abstract: The present invention relates to a method of manufacturing a photoelectric conversion device in which selective dye adsorption can be performed easily. In the step of a dye adsorbing process, a material unit 21 having partition walls of a predetermined shape is placed over semiconductor electrodes 121 to 123, which are a titanium oxide electrode. The material unit 21 is laminated by a UV cure adhesive. Dye solutions S1 to S3 obtained by dissolving each of three kinds of dyes of N719, Black dye, and D149, for example, into a CH3CN/t-BuOH mixed solution are put in each of sections divided by the partition walls. The material unit 21 is inverted in that state, and left standing still for 24 hours. Then, the adhesive is removed after passage of the 24 hours. Thus, the semiconductor electrodes 121 to 123 having regions corresponding to the sections which regions are colored with the three different kinds of dyes are obtained.

  • Patent number: 4430445
    Abstract: Novel imidazolylmethylstyrene compounds which are basic compounds and have excellent resistance to oxidation and high polymerizability are disclosed. The basic compound of the present invention is prepared by reacting a halogenomethyl-styrene with an imidazole compound, and can be used, for example, as a curing agent for epoxy resins. The imidazolymethylstyrene compounds are readily homopolymerized or copolymerized to provide linear homopolymers, linear copolymers or cross-linked copolymers having pendant imidazolylmethylphenyl groups. These polymers have greater resistance to oxidation than the homologues, and are useful as an ion exchange resin, extractant of metals, sizing agent and antistatic agent.
