The presented work concerns the study of solution sheared organic thin film transistors based on a 2,8-difluoro-5,11-bis(triethylsilylethynyl)anthradithiophene (diF-TES-ADT) polymer blend. Four different polymer binders were tested (i.e., polystyrene 10k and 100k g mol−1and poly(methyl methacrylate) 25k and 120k g mol−1) in order to investigate the influence of the polymer binder nature and its molecular weight on the thin film morphology and device performance. Structural analysis by X-ray and Raman spectroscopy combined with atomic force microscopy (AFM) and polarized optical microscopy were used for a complete characterization of the thin films. Additionally, resonance Raman spectroscopy elucidated the isomeric composition of the thin film devices and the different interactions of the organic semiconductor with the polymer binders.

Abstract
The presented work concerns the study of solution sheared organic thin film transistors based on a 2,8-difluoro-5,11-bis(triethylsilylethynyl)anthradithiophene (diF-TES-ADT) polymer blend. Four different polymer binders were tested (i.e., polystyrene 10k and 100k g mol−1and poly(methyl methacrylate) 25k and 120k g mol−1) in order to investigate the influence of the polymer binder nature and its molecular weight on the thin film morphology and device performance. Structural analysis by X-ray and Raman spectroscopy combined with atomic force microscopy (AFM) and polarized optical microscopy were used for a complete characterization of the thin films. Additionally, resonance Raman spectroscopy elucidated the isomeric composition of the thin film devices and the different interactions of the organic semiconductor with the polymer binders.File | Dimensione | Formato | |
