Films of organic polymers were prepared and investigated as insulating layers in contact with phthalocyanines as organic semiconductors for use in organic field effect transistors. The polymer films were obtained either by a high-vacuum technique based on the thermal decomposition of polymers and polymerization of the fragments on a substrate, by the spin-coating of polymer solutions or by the cross-linking of spin-coated precursors. Poly(vinylchloride), poly(vinylidenefluoride), poly(acrylonitrile), poly(methylmethacrylate), poly( N -vinylpyrrolidone), poly(styrene), poly(4-vinylpyridine), poly( N -vinylcarbazole) and a polyimide were used as polymers. The film growth was studied by mass spectrometry and infrared spectroscopy. Electrochemical measurements by cyclic voltammetry served to analyze the properties of the polymer films. The morphology was determined by atomic force microscopy. Interactions of the films with phthalocyaninatozinc ( PcZn ) was analyzed for co-evaporated PcZn in the polymer films, to probe the chemical compatibility of the methods. Subsequently, evaporated PcZn or hexadecafluorophthalocyaninato-oxo-vanadium ( F 16 PcVO ) thin films were studied in detail by UV-vis spectroscopy and by electrical measurements to investigate interface formation, intermolecular coupling and electrical conduction in such films. The applicability of the different polymers as dielectric layers in organic field effect transistors, with phthalocyanines as the active semiconductor thin films, is discussed, based on their dielectric behavior and observed growth characteristics.

Linear polydimethylsiloxane (PDMS) was investigated as a solubilizing group for π-conjugated polymers with the aim of combining high solubility in organic solvents with the molecular packing in solid films that is advantageous for charge transport. Diketopyrrolopyrrole-based copolymers with different contents and substitution patterns of the PDMS side chains were synthesized and evaluated for application in organic field-effect transistors. The PDMS side chains greatly increased the solubility of the polymers and led to shorter d -spacings of the π-stacking in the thin films compared with polymers containing conventional branched alkyl side chains.

In this work gas sensing properties of Langmuir-Schaefer monolayer organic field-effect transistors (LS OFETs) prepared from organosilicon derivative of [1]benzothieno[3,2-b][1]-benzothiophene (BTBT) have been investigated. The monolayer has been deposited using Langmuir-Schaefer method, which results in a uniform low-defect monolayer with excellent electrical performance, hole mobility up to 7 × 10−2 cm2 V−1 s−1, the threshold voltage around 0 V and on-off ratio of 104. Developed sensors demonstrate a long-term stability of a half-year storage under ambient conditions. Preliminary investigations demonstrated that the LS OFETs give instantaneous response on ammonia and hydrogen sulfide at low concentrations. The results reported open new perspectives for the OFET-based gas-sensing technology.
