| Summary: | 碩士 === 國立中正大學 === 化學所 === 98 === In this dissertation, we successfully synthesized BBIDN series of derivatives (structure shown below) in a new synthesis method. We tried to increase the π-conjugated system in this series of derivatives, hoping that these compounds can possess a longer wavelength of absorption and have higher capacity for absorbing sunlight used in solar cells.
We focused on BIDN series of derivatives and new series of BBIDN (structure shown below) to explore the photochromism of these materials. By measuring the UV / visible spectroscopy and electron paramagnetic resonance spectroscopy, we tried to identify the nature of photochromism of this series. And then, we doped BBIDN derivatives in organic photovoltaic solar cells. We found that the efficiency of the solar cells decreased when increasing the proportion of BBIDN materials.
