Thin film transistors (TFTs) can be used to determine the bulk‐like mobilities of amorphous semiconductors. Different amine‐based organic hole transporting materials (HTs) used in organic light‐emitting diodes have been investigated. In addition, the present study also measures the TFT hole mobilities of two iridium phosphors: Ir(ppy)3 and Ir(piq)3. These materials are grown separately on SiO2 and polystyrene (PS). On SiO2, the TFT mobilities are found to be 1–2 orders smaller than the bulk values obtained by time‐of‐flight (TOF) technique. On PS gate dielectric layer, the TFT mobilities are in good agreement TOF data. Only 10 nm of organic semiconductor is sufficient for TFTs to achieve TOF mobilities. Using the Gaussian disorder model, it is found that on SiO2 surface, when compared to the bulk values, the energetic disorders (s) of the HTs increase and simultaneously, the high temperature limits (µ∞) of the carrier mobilities decrease. Both s and µ∞ contribute to the reduction of the carrier mobility. The increase in s is related to the presence of randomly oriented polar Si‐O bonds. The reduction of µ∞ on SiO2 is related to the orientations of the more planar molecules which tend to lie horizontally on the surface.

“…In 2015, a 1.8-inch grayscale flexible multiphoton emission OLED display ( Figure 2 a) with an active-matrix OTFT backplane was developed using solution-shearing and solution processes [9][10]. Careful lyophobic/lyophilic processing of the insulating material, bank structure, and organic semiconductor (OSC) ensured high performance of the OLED display.…”

“…Among these technologies, organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), and organic photovoltaics (OPVs), which use organic materials, have been investigated for flexible devices [6][7][8], and their development is underway. In particular, interest in flexible OLED displays is increasing [9][10][11]. An institution of Yamagata University, Smart MIRAI House, was built to demonstrate the research results for living labs and the living environment of the near future, as shown in Figure 1 [12].…”

Copper phthalocyanine (CuPc) amorphous film was successfully deposited on a silicone substrate by physical vapor deposition. When the film was in contact with a common solvent such as aniline, 1-propanol and toluene, the CuPc solid film was partially dissolved followed by nucleation and crystal growth in the solution. Based on these experimental results, we propose a novel method for preparation of the organic thin film by combination of dry and wet processes.
