| Summary: | 碩士 === 國立暨南國際大學 === 應用化學系 === 100 === In this work, we cross-coupled a variety of N, N-dimethyaniline and its derivatives with zinc porphyrins and fluorene by using Sonogashira cross-coupling method. The UV - visible absorption spectra, fluorescence emission spectra, electrochemical and photovoltaic properties of these compound are also studied these compounds can be divided into three categories by their structure and application, zinc porphyrins photosensitizer, organic photosensitizers and the zinc porphyrins for electrochemical polymerization.
The device using the LD14 dye shows short-circuit current of 20.397 mAcm-2, the open-circuit voltage of 0.710 V, and the fill factor of 69.40. The overall efficiency was determined to be 10.05%.
For the organic photosensitizer, the UV - visible absorption maxima, the fluorescence emission wavelengths, electrochemical properties and photovoltaic properties of FLN1, FLN1, 'FLN2 and FLN2' are very similar. FL3N and FLN3 show more red-shifted absorption wavelength due to the extended conjugation. The overall efficiencies were determined to be 4.20% and 3.98% for FL3N and FLN3, respectively, about 57% and 54% of N719 under the same experimental conditions.
Two zinc porphyrin compounds modified by N, N-dimethyaniline and its derivatives, namely APE-3 and the APE-5, werestudied for their electrochemical polymerization.
