| Outline of Final Research Achievements |
To construct an NO sensing device applied on the human body, a sensing molecules (metal complexes) with high NO selectivity were modified onto an electrode surface. Phosphonium ion with long alkyl chains was used as a modifier on the electrode together, which was possible to form spaces for the incorporation of sensing molecules by the steric hindrance between the alkyl chains. Three sensing molecules was prepared in this study, but two of them showed high NO selectivity. So, they were used for the preparation of the sensor. It was found that the electrode with a Co(III) complex with N2S2 coordination environment could detect 10~150 ppb of NO. Furthermore, TiO2 light-transparent electrode modified by the phosphonium also captured dye complex and the performance as the dye sensitized solar cell was improved by changing the alkyl chain length, which suggests that it is one of the important factors to optimize the sensing condition on TiO2 electrode.
