“…Also, the HOMO is localized mostly on the carbazole moiety, suggesting a stronger electron-donating property of this unit relatively to thianthrene. This is consistent with the electrochemical characteristics of the molecule (Figure S12) indicating nonreversibility − of the oxidation process as typically for carbazole. , HOMO located on the thianthrene would result in a reversible oxidation cycle. , LUMO is on the other hand situated on the thianthrene moiety.…”

Observation of Dual Room Temperature Fluorescence–Phosphorescence in Air, in the Crystal Form of a Thianthrene Derivative

Thianthrenes have been nearly forgotten as phosphors in recent years, but are now coming back, showing their strong potential in luminescent applications. Here, we present a comprehensive photophysical study of a carbazolyl derivative of thianthrene in different matrices and environments. The diffusion of oxygen is slowed down in the rigid environment of thianthrene organic crystals suppressing their phosphorescence quenching, as well as triplet-triplet annihilation. This facilitates the observation of simultaneous fluorescence and phosphorescence emissions at room temperature, in air, giving origin to strong white luminescence. Moreover, the color coordinates of the dual fluorescence-phosphorescence white emission, which is observed only in rigid amorphous media and in crystals, can be tuned.

“…Organic semiconductors are divided into two main classifications: low molecular weight compounds and polymers. Both categories have a common property which is the presence of a conjugated system of πbond formed from P-orbitals of carbon atoms of trigonal hybridization [15,21,22]. Following the literature, polyaniline (PANI), pentacene, poly (3-hexylthiophene) (P3HT), poly (3-alkylthiophene) (P3AT), and poly (3-octylthiophene) (P3OT) are the most commonly used OSCs in OFET technology [23].…”

Organic field effect transistors (OFETs), used in the fabrication of nano-sensors, are one of the most promising devices in the field of organic electronics, because of their light weight, flexible and low fabrication cost. However, the optimization of such OFETs is still in an early stage due to the very limited analytical as well as numerical models presented in the literature. This research presses to demonstrate a numerical carrier transport model based on finite element method (FEM), to investigate the I-V characteristic of OFETs. Two various organic semiconductor materials have been included in the study, polyaniline and pentacene, where a micro-scale as well as a nano-scale models have been presented. OFETs have been studied in terms of channel length, dielectric thickness, and doping level impact. We nominated the threshold voltage, the on/off current ratio, the sub threshold swing, and the field effect mobility’s as the main output evaluating parameters. The numerical model has shown the criticality of the doping effect on tuning the device flowing drain current, to exceed 300 μA saturation current, along with threshold voltage of -0.1 V under a channel length of 30 nm. Additionally, the study highlights the effectiveness of the polyaniline over pentacene as nano-channel length OFET, due to the boosted conductivity of polyaniline with respect to pentacene.

Abstract1,4-Dithiin and its dibenzo-analogue, thianthrene, represent a class of non-aromatic, sulfur-rich heterocycles. Their unique properties, stemming from both their non-planar structures and reversible one- and two-electron oxidations, serve as primary motivators for their use in the development of new materials. The applications of 1,4-dithiins and thianthrenes are rich and diverse, having been used for energy storage and harvesting, and the synthesis of phosphorescent compounds and porous polymers, among other uses. This review offers first an overview of the properties of 1,4-dithiin and thianthrene. Next, we describe enabling synthetic methodology to access 1,4-dithiins and thianthrenes with various substitution patterns. Lastly, the utility of 1,4-dithiin and thianthrene in the construction and design of new materials is detailed using select literature examples.1 Introduction2 Properties of 1,4-Dithiins and Thianthrenes3 Synthesis of 1,4-Dithiins and Thianthrenes3.1 Synthesis of 1,4-Dithiins3.2 Synthesis of Thianthrenes4 Application of 1,4-Dithiins and Thianthrenes in Materials4.1 Thianthrene-Containing Polymers4.2 Thianthrene in Redox-Active Materials4.3 Thianthrenes and 1,4-Dithiins in Supramolecular Chemistry and Self-Assembly4.4 Thianthrenes in Phosphorescent Materials4.5 Thianthrenes with Other Interesting Photophysical Properties4.6 Thianthrenes in the Synthesis of Non-natural Products5 Conclusion
