Summary: Monolayer molecular crystals (MMCs) have aroused global research interest due to their unique properties. Compared with their bulk counterparts, MMCs have lower contact resistance, making them ideal carriers for studying the intrinsic properties of organic semiconductors. However, studies on anisotropic charge transport in MMCs are still rare. In this study, by non-destructively preparing electrodes on MMCs, anisotropic charge transport properties of two typical MMCs were obtained, providing a basis for realizing high performance device arrays with low device-to-device variation.

Summary: In this study, we systematically investigated the strain-induced carrier mobility of two organic semiconductors and revealed their relationship with intermolecular packing configurations. The results showed periodic changes of the strain-induced carrier mobility, which can be attributed to the alternating phase changes of molecular orbital interactions. These findings are of significance for optimizing carrier mobility modulation and the development of organic electronic devices.

Summary: In this study, the theoretical investigation of the single-triplet excited state transition process of novel anthraquinone compounds in solution was conducted by analyzing the effects of energy gap (ΔE-ST) and spin-orbit coupling (SOC). It was found that the molecular conformation, steady-state spectra, and molecular orbitals were influenced by substituents, leading to changes in ΔE-ST and SOC. The presence of benzene in donor units and enhanced conjugation were shown to decrease ΔE-ST and increase SOC in different anthraquinone compounds.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
