Summary: This study fabricated blend films of TIPS pentacene/PMMA using electrostatic spray deposition (ESD) and deposited a thin film of MoO3 on the surface of the active layer. The results showed that MoO3 deposition caused the formation of a surface channel and increased the off-state current in OFETs. The study also found that Mo atoms penetrated TIPS pentacene and oxidized to MoO(x), enhancing charge transfer between neighboring TIPS pentacene molecules. The off-state current could be modulated by changing the ambient condition.

Summary: In this study, a large area patterned hydrogen-bonded organic framework (HOF) film was successfully fabricated on unmodified conductive substrates using an efficient and low-cost electrostatic spray deposition (ESD) method. By combining ESD with a template method, various patterns of HOF films, including deer and horse shapes, were easily produced. The obtained films showed excellent electrochromic performance and could change color quickly. Based on these films, a large-area patterned EC device was constructed, demonstrating practical potential application. The presented ESD method can be extended to other HOF materials, providing a feasible path for the construction of large-area patterned HOF films for optoelectronic applications.

Summary: 2,9- and 2,10-diphenylpentacene were synthesized and studied as main active components in organic field effect transistors. Diphenyl substitution of pentacene affects the unit cell dimensions slightly and both isomers self-assemble into nanoribbons during thin film growth. The 2,9-isomer exhibited similar hole mobility to unsubstituted pentacene, while the 2,10-isomer showed lower field effect mobility. The diphenyl substitution did not lead to the same enhancement in field effect mobility as observed in anthracene.

Summary: This study investigated eight axially substituted SiPcs and their application in solution-processed n-type OTFTs. It was found that the length of the alkyl chain affects device performance and thin-film morphology, and the effects of high-temperature annealing and spin coating time on film formation were explored. The study also revealed that thermal annealing and spin time significantly impact film crystallinity, morphology, and device performance, with bis(tri-n-butylsilyl oxide) SiPc showing the highest electron field-effect mobility among the studied materials.

Summary: Four substituted nonacenes with strategically placed triisopropylsilyl-ethynyl groups were synthesized and characterized. These compounds are the most stable and soluble nonacenes to date. They exhibit stability for several weeks in the solid state and have a half-life of 5-9 hours in dilute solution. Crystal structure analyses confirmed the structures of two nonacene derivatives. One derivative was tested as a thin-film transistor material and showed ambipolar charge transport. The stability of soluble nonacenes was achieved through triisopropylsilyl-ethynylation, halogenation, and methoxylation.

Summary: We report the synthesis and characterization of four novel n-type polymer semiconductors containing a 2-(1,3-dithiol-2-ylidene)malonitrile (DTYM) group as an acceptor and a 2,1,3-benzothiadiazole (BT) unit. The introduction of the DTYM group leads to backbone twisting and blue-shifted absorption, but increases the dipole moment and electron affinity. All polymers exhibit n-type semiconducting character in organic field-effect transistors (OFETs), with the fluorinated bithiophene donor demonstrating the best performance. This work highlights the influence of the DTYM group on polymer semiconductors and its potential as a functional group to enhance electron affinity.

Summary: In this work, a new synthesis method for a key building block of the ring-expanded electron-deficient pentacyclic azepinedione (BTTA) was reported. Three copolymers of BTAA with different side chains were prepared and their performance in transistor and photovoltaic devices were studied. The best-performing polymers in transistor devices exhibited maximum saturation hole mobilities of 0.027 and 0.017 cm(2) V-1 s(-1), and the best photovoltaic efficiency achieved was 6.78% for pBDT-BTTA-3-based devices. The use of a low band gap non-fullerene acceptor (BTP-eC9) resulted in improved efficiency of up to 13.5%. These results demonstrate the versatile applications of the electron-deficient BTTA unit in organic electronics.
