In this work, we introduce a computational framework that probes the bimolecular potential energy landscape of candidate molecules, enabling us to dissect the role of directional intermolecular interactions in establishing polar order. In closely related families of materials we find conflicting preferences for (anti)parallel ordering which can be accounted for by specific interactions between molecules.

Remarkably, it is revealed that enantiopure SubPcs exhibit a reduced tendency to form LC phases compared to their racemic counterparts, whereas higher substitution density increases flexibility within the columns, compromising coaxial alignment. Moreover, we find that the use of conformationally flexible, π-extended peripheral substituents enables efficient π–π stacking, and that the incorporation of hydrogen-bonding amide groups leads to highly stable mesophases with elevated melting points, although the mesophase remains at room temperature after thermal treatment.

The European Union and other countries have restricted the use of CPL in animal husbandry due to concerns about antibiotic resistance. Hence, monitoring CPL in animal food and environmental water samples is highly essential. In this context, we developed a low-cost sensing matrix of oxygen-deficient tin oxide (DSnO<small><sub>2</sub></small>) nanoparticles to determine CPL. The existence of oxygen deficiency was confirmed using various physicochemical characterization techniques. Electrochemical studies were performed by different voltammetry techniques, such as CV, LSV, and DPV, for CPL detection using DSnO<small><sub>2</sub></small>/GCE. The voltammetry results deduce that under optimal conditions, DSnO<small><sub>2</sub></small> can readily interact with the nitro group of the CPL molecule, which increases the sensitivity towards CPL detection. The designed sensor showed a wide linear range of 0.1–35 μM with an LOD value of 0.094 μM.

To address these drawbacks, this paper proposes an interfacial-spreading method based on the Marangoni effect, aimed at achieving highly uniform gate dielectrics on both flat and curved substrates. Using only ∼11 μL of the precursor solution, crosslinked poly(4-vinylphenol) (CL-PVP) films were successfully fabricated. The prepared films exhibited a thickness coefficient of variation of 0.04, four times lower than that of spin-coated films (0.17). Additionally, the CL-PVP gate dielectric could be mechanically patterned. The interfacial-spreading method minimized thickness variations and reduced material consumption by approximately tenfold in relation to spin coating. Organic-semiconductor-based transistors fabricated using the interfacial-spread CL-PVP gate dielectrics demonstrated performance comparable with those prepared using spin-coated films. Furthermore, a complementary-type inverter was fabricated to validate the functionality of the prepared films in electronic circuits. The CL-PVP gate dielectric could be successfully deposited on curved substrates (radius of curvature of up to 7.5 mm), displaying a thickness nearly identical to that on flat substrates and comparable with that on spin-coated films.
