Organic semiconductors(OSCs) are significant systems of next-generation optoelectronic materials, which are widely applied in flexible devices, power generation and sensors. However, most of the organic semiconductors are prepared in chlorinated solvents which are harmful to human health and ecological environment. Nowadays,accompanied with the trends of environmentally-friendly optoelectronics, the OSCs processed with green solvents attracted extensive attention and developed rapidly. In this article, we reviewed the advances in environmentally-friendly OSCs in molecular design, solvent selection and processing method. The application of those materials in organic thinfilm transistor and organic thermoelectric devices was highlighted. Finally, challenges and perspectives of the environmentally-friendly OSCs are also summarized.
