The phase segregation as a result of mixing organic semiconductors with polymeric additives has been reported as an intriguing avenue to optimize semiconductor crystal microstructure, active layer composition and charge carrier transport. In this work, we report the mixing of organic semiconductor 6,13‐bis(triisopropylsilylethynyl) pentacene (TIPS pentacene) with poly(butylacrylate) as a polymer additive to control the semiconductor crystal growth and morphology. The incorporation of poly(butylacrylate) induces a vertical phase segregation but a more predominant lateral phase segregation with TIPS pentacene. Along with a solvent vapor annealing technique, poly(butylacrylate) evenly distributes the semiconductor nuclei on the polymer matrix, and results in organic crystal with enlarged grain width. In addition, the randomized crystal growth of TIPS pentacene has been significantly reduced, giving rise to a 25‐fold decrease in misorientation angle. The bottom‐gate, top‐contact thin film transistors with the poly(butylacrylate)/TIPS pentacene mixture as the active layer demonstrated an improved hole mobility of 0.11 cm2/Vs. We believe the phase segregation induced by the poly(butylacrylate) polymer as well as the solvent vapor annealing method as reported in this work can be facilely replicated on other organic semiconductors to realize high performance organic electronic device applications.

“…The research of solution-processed organic semiconductors has achieved unprecedented progress in recent years [1][2][3][4][5][6][7]. Specially, they have been demonstrated with properties that would greatly benefit application in organic thin-film transistors (OTFTs), which include improved charge-carrier mobilities and expanded solubility in organic solvents [8][9][10][11]. Despite these advantages, their implementation in organic electronics devices still has many restrictions, which can be attributed to problems including crystal misorientation, morphological nonuniformity and low charge-carrier mobility [12,13].…”

Recently, the research in solution-based, small-molecule organic semiconductors has achieved great progress, although their application in organic electronics devices is still restricted by a variety of issues, including crystal misorientation, morphological nonuniformity and low charge-carrier mobility. In order to overcome these issues, hybrid material systems that incorporate both organic semiconductors and additives have been successfully demonstrated to control crystal growth and charge transport of the organic semiconductors. In this work, we first review the recent advances in the charge-carrier mobility of the organic semiconductors, followed by a comparison of the different additives that have been reportedly blended with the semiconductors, including polymeric additives, small-molecule additives and nanoparticle based additives. Then we will review the important nanoparticles employed as additives to blend with solution-based, organic semiconductors, which effectively improved the semiconductor crystallization, enhanced film uniformity and increased charge transport. By discussing specific examples of various well-known organic semiconductors such as 6, 13-bis (triisopropylsilylethynyl) pentacene (TIPS pentacene), we demonstrate the essential relationship among the crystal growth, semiconductor morphology, dielectric properties, and chargecarrier mobilities. This work sheds light on the implementation of nanoparticle additives in highperformance organic electronics device application. the application of the organic semiconductor in thin-film transistor and other electronics device fabrication. Throughout the discussion of these specific examples that mainly involve small-molecule organic semiconductors, we showcase that this work can be used to control the crystallization and electrical performance of other newly-discovered, high-performance, semiconducting materials. Advances in organic electronicsIn this section, we will review the various advances in charge-carrier mobilities and device application that have been recently achieved in the field of organic electronics. The following discussion will be mainly focused on various solution-processed, small-molecule, organic semiconductors.The mobilities in solution-processed, small-molecule, organic semiconductors have been reported to be compared to or even far surpass the mobility of amorphous silicon. For example, Asare-Yeboah et al developed a temperature-based method which exposed the substrate to a gradient temperature and induced a solubility difference of a p-type small-molecule semiconductor 6, 13-bis (triisopropylsilylethynyl) pentacene (TIPS pentacene) [18]. TIPS pentacene crystals grew from the lower temperature side of the substrate towards the higher temperature side, forming well-aligned ribbons across the whole substrate. A mobility of up to 0.5 cm 2 V −1 s −1 has been reported from the TIPS pentacene OTFTs based on an ITO/PET flexible substrate by using the temperature-based alignment technique. Wade et al demonstrated a zone casting metho...
