In this article, we provide an in-depth review of important works on phase segregation which occurs as a result of mixing organic semiconductors with polymeric additives. Throughout the discussion, the indispensable correlations among phase segregation, crystal growth, layer structure and film morphology are showcased using specific examples that mainly entail small-molecule organic semiconductors such as 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS pentacene) and 2,8-difluoro-5,11- bis(triethylsilylethynyl)anthradithiophene (diF-TES-ADT). |
