Triazatetrabenzocorroles (Tbc) consist of a class molecules derived from the phthalocyanine and porphyrin families that are less commonly synthesized utilized in applications for organic electronics. In this work, we have oxy phosphorus Tbc (POTbc) integrated it as an semiconductor thin film transistors (OTFTs). Both bottom-gate bottom-contact (BGBC) top-contact (BGTC) OTFTs fabricated with POTbc resulted clear p-type performance both air under inert conditions. A series solution-based silanes thermally evaporated p-sexiphenylene were dielectric surface treatments means to modify energy prior depositing films. Other fabrication conditions also explored, such deposition rate POTbc, substrate temperature during deposition, post-deposition annealing. Of these, optimized POTbc-based obtained n-octadecyltrichlorosilane (ODTS)-coated substrates, heated which afforded average field effect mobility 8.18 × 10–3 cm2 V–1 s–1 threshold voltage −23.2 V. X-ray diffraction polarized Raman microscopy indicated significant increase crystallinity morphology more molecular face-on configuration when deposited on ODTS-treated surfaces. These results represent first report using including structure–property relationships related optimization device performance.

An extremely sensitive ammonia (NH3) sensor was developed by using an aligned nanowires/thin film hybrid channel of organic thin transistor (OTFT). Conjugated polymer poly(2,5-bis(3-tetradecylthiophen-2yl)thieno(3,2-b)thiophene) (PBTTT-C14) has been used as semiconductor that fabricated via "floating transfer method" (FTM). The crystalline fibrillar microstructure within the liquid phase mixed solvent, which self-assembled on air–liquid interface through FTM method. This structured then transferred a cleaned Si/SiO2 substrate, whereas Au source–drain electrodes this OTFT. To investigate sensing behavior designed OTFT, various low concentrations NH3 have exposed ranging from 0.2 to 5 ppm. From accumulation mode drain current variation, it observed is toward gas with response about 75% at ppm, limit detection (LOD) ∼0.67 confirms its applicability lower concentrations. More interestingly, depletion OTFT reduces ∼200 times during investigation, ∼40 larger variation than current. Additionally, these variations excellent linearity concentration. also exhibits selectivity and sensitivity gas, can satisfy requirements for real-world applications.

Abstract Understanding the complex relationships underlying performance of organic electronic devices, such as field‐effect transistors (OFETs), requires researchers to navigate a multi‐dimensional parameter space that includes material design, solution formulation, fabrication parameters, and device geometry. Herein, recently developed materials acceleration platform is demonstrated, named RoboMapper, perform direct on‐chip OFETs by ultrasonic meniscus printing using silicon phthalocyanine (SiPc) derivatives semiconductor. bis(tri‐ n ‐butylsilyl oxide) SiPc ((3BS) 2 ‐SiPc) exhibited best characterized highest electron mobility ( µ e ). Through optical microscopy grazing‐incidence wide‐angle X‐ray scattering (GIWAXS), favorable (3BS) ‐SiPc attributed specific film morphology molecular packing achieved with optimal print conditions. Investigating impact deposition parameters reveals crucial role solvent evaporation rate speed in achieving high‐quality formation. Overall, conditions for devices include slow speeds fast evaporating solutions mixture co‐solvents an elevated substrate temperature. The results this work reveal distinct between conditions, properties, each derivative emphasize necessity high throughput experimentation comprehensively understand process‐performance semiconductors.
