From benzobisthiadiazole, thiadiazoloquinoxaline to pyrazinoquinoxaline based polymers : effects of aromatic substituents on the performance of organic photovoltaics
Here we report the syntheses of low bandgap polymers based on benzobisthiadiazole (BBT), thiadiazoloquinoxaline (TQ) and pyrazinoquinoxaline (PQ) core structures with different aromatic substituents. The effects of changing core structures from BBT to PQ and also substituents from biphenyl and bithi...
