Herein, the structure of an o-xylene C60 monoadduct (OXCMA) having high electron mobility in solution-processed devices was studied by single-crystal X-ray analysis. The crystal of OXCMA showed a well-aligned three-dimensional network of the C60 moiety without inclusion of solvent molecules. Density functional theory (DFT) methods and hopping modeling were employed to calculate the charge carrier mobility of OXCMA with good agreement with the experimental mobility.

An organic field-effect transistor (OFET) toward phosphate sensing has been successfully developed. The fabricated OFET possessing an extended-gate functionalized with zinc(II)-dipicolylamine (ZnII-DPA) exhibited an electrical and cross-reactive response to phosphate anions such as nucleotides and inorganic phosphates over halide ions in water. The results obtained here indicate that OFET could be a powerful platform for phosphate sensing based on supramolecular interactions. [ABSTRACT FROM AUTHOR]

Solution-processable polymers based on strong acceptor benzobis(thiadiazole) (BBT) units were synthesized to form unipolar n-type organic thin-film transistors (OTFTs) that were electronically characterized. These polymers exhibited a narrow band-gap and low LUMO level, resulting in distinct n-type semiconducting properties within the OTFT devices. The BBT-thiazole polymer material showed better electron transport than BBT-thiophene polymers. The use of electron-deficient units was found to be suitable for the realization of the unipolar n-type semiconducting polymers. [ABSTRACT FROM AUTHOR]
