Organic semiconductors (including both small-molecules and polymers) have been widely investigated toward various promising applications beyond the well-established organic light-emitting diodes. In this talk, I will first introduce our recent works on solution-processable organic thin-film transistors, including the control of n-channel transistor characteristics using newly synthesized imidazole-based donor dopants and the fabrication of homojunction transistors using the polymer stamping method. Then, the investigation of the relationship between structure and cross-plane thermal conductivity in doped polymer semiconductor films will be explained. Besides I will also mention our results on photocatalytic hydrogen and clean fuel production by carbon dioxide reduction using polymeric carbon nitrides, that arealso classified as n-type polymer semiconductors.
