“…These materials belong to a larger class of PF derivatives within which the injection and transport of holes is modified by the incorporation of arylamines, either blended in the active layer or incorporated into the polymer chain. 13 Triarylamines are known to be good hole conductors 14 and are commonly used as hole transport layers. 2,15 Hole mobilities up to 3 Â 10 À7 m 2 /Vs have been measured in fluorenetriarylamine copolymers.…”

“…Aromatic amines play a central role in many areas of modern day organic chemistry, including such diverse fields as polymers, photography, medicine and materials [1][2][3]. Arylamines can be obtained either by the copper-catalyzed Ullmann condensation or palladium-catalyzed cross-coupling reactions [4][5][6][7][8][9].…”

Source of materialTo a 25-mL sidearm flask in a dry nitrogen box were added 3-bromo-benzo [de]anthracen-7-one (2.5 mmol), diphenyl-amine (2.50 mmol), Pd(CH 3 COO)2 (0.025 mmol, Pd/Br = 1 %), tri-tertbutylphosphine (0.03 mmol), and sodium fórí-butoxide (3.0 mmol). The flask was sealed with a septum and was then moved out of the nitrogen box. o-xylene (10 mL) was injected via a syringe. The reaction mixture was heated and stirred at 120 °C under nitrogen until the reaction was completed. The reaction mixture was then cooled to room temperature, Altered through a mixture of celite and silica gel pad, and washed with dichloromethane. The fíltrate was then washed with water and dried by MgSC>4. Concentration of the filtrate on a rotary evaporator followed by washing of the solid material with methanol afforded the desired crude product. The crude product was then dried at 120 °C in a vacuum and further purified by sublimation. Red crystals were obtained by sublimation at (4...6)-10" 3 Pa for 16 h.

“…There are several reports describing the photochemical or thermal crosslinking of organic side chain polymers to form insoluble polymer networks as charge-transport and/or emission layers [1][2][3][4]. However, the photochemical crosslinking process often caused a substantial degree of photochemical degradation and a reduction of charge-carrier mobility.…”

The development of organic field-effect transistors (OFETs) and organic photovoltaic cells (OPV) has seen much progress using solution-processable organic semiconductors, which can combine high charge transport mobility, stability and patternability. In this work, we report on the design and synthesis of a new type of photopatternable π-conjugated cruciform molecule. These molecules are capable of photopatterning by virtue of photopolymerization of the reactive end-groups (pentadien or acrylate). Their solubility is very good for solution processing. Transistor devices using these molecules provided a maximum field-effect mobility of 3.7 × 10 −3 cm 2 V −1 s −1 as well as a high current on/off ratio. Remarkably, it was found that their charge carrier mobilities were well-maintained, even after the photocrosslinking process.
