Summary: A template-free method for electrochemical deposition of P3HT has been developed. Electrodeposition is preceded by an electrochemical nucleation step, enabling the production of a uniform film without the need for pre-treatment of the electrode surface. The resulting film is highly nanostructured, conductive, and easily delaminates for analysis. This technique offers a simple route to conductive organic films for various applications.

Summary: This study introduces a new technology to improve electrical properties during stretching by using oriented P3HT films and PDMS layers. It was found that the electrical stability of P3HT films during stretching is better when stretched perpendicular to the c-axis. In addition, the evolution of the multiscale structure of P3HT films under stretching conditions was explored.

Summary: Aerogels containing P3HT nanofibers in a PS matrix were fabricated by freeze-drying and doped with iodine vapor. The aerogels exhibited low thermal conductivity and high Seebeck coefficient, showing potential for thermoelectric applications. The relationship between Seebeck coefficient and conductivity varied at different dopant concentrations, with a giant Seebeck coefficient attributed to unique morphology and energy filtering effects.

Summary: Poly(3-hexylthiophene) (P3HT) was synthesized by chemical oxidative polymerization using ferric chloride (FeCl3) as the oxidizing agent and various surfactants as shape templates. The effects of mole ratios, polymerization times, and surfactant types and concentrations on the electrical conductivity and particle properties were investigated. The results showed that P3HT synthesized with dodecylbenzenesulfonic acid (DBSA) at Critical Micelle Concentration (CMC) 6 had the highest electrical conductivity and particle size of 1530 +/- 227 nm. The thermal analysis revealed that surfactant-synthesized P3HT had higher stability and char yields. The electrical conductivity of DBSA-synthesized P3HT was further enhanced by doping with HClO4.

Summary: We have conducted a study on the dynamics of poly(3-hexylthiophene) (P3HT) monolayers at the interfaces between highly oriented pyrolytic graphite (HOPG) and P3HT solutions in 1,2,4-trichlorobenzene using scanning tunneling microscopy (STM). Real-time STM observation at room temperature has shown that P3HT molecules adsorbed on graphite exhibit substantial mobility even in densely packed conditions, leading to significant fluctuations of the self-organized monolayer of P3HT. Our findings demonstrate that in the monolayers, the orientational order is limited to a short range comparable to the polymer chain length. We have also conducted kinetic Monte Carlo simulations based on a 2D semiflexible lattice polymer model to explain our observations.

Summary: This study introduces a novel strategy of spinodal decomposition to create a poly(3-hexylthiophene)/perovskite (P3HT/PVK) heterointerface, effectively reducing energy and carrier losses in perovskite solar cells (PSCs). The P3HT/PVK heterointerface improves energy alignment, reducing energy loss at the interface, and the interpenetrating structure bridges a transport channel, decreasing carrier loss at the interface. This innovative approach achieves a remarkable power conversion efficiency of 24.53% for PSCs.

Summary: This report focuses on the synthesis of a novel material, TTT-co-P3HT, as a donor material for organic solar cells. The synthesized TTT-co-P3HT showed potential with broader electrochemical and optical band-gaps compared to P3HT, but exhibited insufficient electron/hole separation and charge transfer. Ultimately, the devices using TTT-co-P3HT had a significantly lower power conversion efficiency than those using P3HT.

Summary: Nanoconfinement is an effective strategy to control the orientations and orderings of conjugated polymers (CPs). The study investigates the chain orientations of two crystal polymorphs, Form I and Form II, in poly(3dodecylthiophene)s (P3DDTs) using a porous anodic aluminum oxide (AAO) template. The results show that the pore diameter of the AAO template and the regioregularity (RR) of P3DDTs affect the orientational changes of Form I and Form II crystals, providing guidelines for achieving CPs with controlled intermolecular assembly and chain orientations.

Summary: For the first time, an organic semiconductor, regioregular poly(3-hexylthiophene) (rrP3HT), based excitonic transistor on a piezoelectric YZ lithium niobate substrate is reported. The surface acoustic wave (SAW) field ionizes the excitons, storing the charge pair in the SAW modulated potential field in the semiconductor and carrying them forward. Long-range transport up to 4.7 mm at room temperature has been demonstrated. Exciton flux can be electrically controlled using SAW propagating through a dual metal-insulator-semiconductor (MIS) structure. The device's working mechanism has been verified through numerical analysis using MATLAB and its potential use as an all optical device has been electrically confirmed with additional electrode terminals at the output end.

Summary: A demonstration of an organic semiconductor-based monolithic SAW convolver is reported. The low availability of intrinsic free charge in the organic semiconducting polymer allows for depletion mode operation, enhancing the nonlinear interactions. High efficiency convolved signals were observed for input signals with different combinations of frequencies, without the need for an applied bias. The experimental results and convolution mechanism were verified through numerical analysis in MATLAB.

Summary: The melt-crystallization of conjugated polymers is a potential environmentally-friendly solution processing alternative. However, the specific role of molecular attributes and control strategies are not well understood. This study shows that the effects of chain length on crystallization depend on the amount of chain defects. Melt self-seeding can manipulate the crystallization temperature, especially for longer and more defective chains. Overall, controlling and reporting regioregularity and molecular weight are crucial.

Summary: Understanding the interactions between cancer cells and smart substrates is important for both physiology and pathology. In this study, two phenylboronic acid (PBA)-functionalized films with different surface topographies were successfully fabricated, and the adhesion kinetics of HepG2 cells on these films were analyzed using quartz crystal microbalance with dissipation (QCM-D). The results showed that the PBAS film promoted cell adhesion and spreading, and the cell detachment behavior could be controlled in the presence of glucose based on molecular recognition. The glucose-responsive PBAS film has potential applications in cell-based diagnostics and tissue engineering. Furthermore, QCM-D was proven to be a useful tool for real-time monitoring and analysis of cell-substrate interactions.
