Summary: In this study, the precise film morphologies of organic charge transfer complexes (CTCs) grown on intercalated graphene are investigated using a global ab initio structure search method. By approximating the complex substrate with charged freestanding graphene, the stable structures of prototypical electron acceptor/donor molecules on supported graphene are identified. It is found that the molecules physisorb to graphene in various configurations, indicating the important role of molecule-molecule interactions in film formation.

Summary: Two-component organogels and xerogels based on a C-3-symmetric pyrene-containing gelator were deeply characterized through various techniques, with the gelation phenomenon being highly dependent on the nature of the electron poor dopant. The donor-acceptor interactions play a key role in the formation of gels and their spectroscopic properties, showing a remarkable correlation between phase transition temperatures and the disappearance of charge transfer bands. The luminescent properties of these materials can be tuned with temperature, either in intensity or emission wavelength.

Summary: Charge-transfer assemblies (CTAs) are a new class of functional materials with excellent optical properties and great promise in the biomedical field. In this study, red-shifted porphyrin phototherapeutic agents were successfully prepared by optimizing the stoichiometric ratios of donor-acceptor. These agents exhibited enhanced absorbance in the near-infrared (NIR) region and demonstrated the capacity for both photodynamic and photothermal therapy. This modular assembly method provides an alternative strategy for enhancing the application of phototherapeutic agents.

Summary: Surface X-ray diffraction provides unambiguous structural information when studying the phenomenon of metal substrate adatom incorporation into molecular overlayers. Experimental evidence from scanning tunneling microscopy can be ambiguous and lacks quantitative information. The structural study of the Au(111)-F4TCNQ system shows agreement between experimental and theoretical data, providing insight into the height and conformation of the adsorbed molecule.

Summary: In this study, the micro-structured organic charge-transfer complex TTF-TCNQ was used as the cathode material in aqueous zinc-ion batteries (AZIBs) and its ionic storage behavior was systematically investigated from -40°C to 25°C. The TTF-TCNQ complex showed much better rate and cycling performance than individual moieties, especially at low temperatures, due to its higher electrical conductivity and ionic diffusivity, smaller charge transfer resistance, and lower activation energy. The reaction mechanism was explored through various techniques, confirming the reversibility of the redox reaction involving the C-N and C-S groups. This research not only provides a new choice for AZIBs at low temperatures but also broadens the application field of charge-transfer complexes.

Summary: The (N-Xy-Qn)(TCNQ)(2) anion-radical salt with tetramerized stacks of TCNQ acceptor molecules was successfully synthesized and characterized using vibrational spectroscopy and electrical resistivity measurements. Analysis of the crystal structure data revealed non-uniform charge distribution, with -0.83 e localized on the inner B molecules and -0.33 e on the outer A molecules. The infrared and Raman spectra were dominated by TCNQ vibrational modes and exhibited splitting related to the tetramerized structure. The material exhibited low-conducting behavior with a room temperature conductivity of 2.6 mS cm(-1), and the temperature dependence of resistivity could be explained by the band conduction model. The estimated charge distribution based on crystal data was confirmed by other charge-sensitive modes.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
