| Research Abstract |
In this research subject, we have tried to develop a chemical UV actinometer that enables simple and accurate determination of the intensity of UV -region-light involved in solar irradiance. We developed a new sensor molecule containing an azide moiety that selectively absorbs UV -region-light and undergo photoreaction to be transformed to a colored species. This molecule thus allows simple and accurate determination of UV light intensity by UV -vis spectral analysis.
