Summary: Three non-classical amphiphilic phenylazoimidazole derivatives were synthesized and their in-situ molecular assemblies upon coordination with AgNO3 at the air/water interface were investigated. These compounds showed good photochromic properties and formed H-aggregates on the surface despite lacking alkyl chains. The Ag(I)-coordinated 4-PRIM films exhibited supramolecular chirality due to pi-pi stacking between neighboring azophenyl imidazolium units and symmetry breaking in some systems.

Summary: Novel fluorescent Langmuir-Blodgett (LB) films have been constructed from different amphiphilic dicynaoquinodimethanes (DADQs), and the relationship between film structure and fluorescence properties, as well as the response of the films to non-fluorescent target analytes, has been studied. The results show that the modulation of fluorescence varies for different films, which can be attributed to restricted non-radiative decays or charge transfer reactions between target analyte and film.

Summary: This study investigated the effects of potassium ions on the surface properties of Amphotericin B (AmB) using the Langmuir monolayer method. The results showed that potassium ions enhance the influence of AmB on membrane stability at low surface pressures but weaken it at high surface pressures. Potassium ions also significantly interfere with the interaction between AmB and the cholesterol-enriched region.

Summary: A novel phthalonitrile with a 26-member tetraoxadithia macrocycle moiety was synthesized and cyclomerized to obtain a new zinc(II) phthalocyanine. Characterization of the novel phthalocyanine and precursor compounds was conducted using various techniques. Langmuir-Blodgett (LB) thin films were fabricated using the 26-membered phthalocyanine to investigate its gas sensing properties. The sensor parameters and the thickness effect on the gas sensing mechanism were examined using Quartz Crystal Microbalance (QCM) technique. Experimental measurements of QCM kinetic were validated using a nonlinear autoregressive with exogenous input neural network.

Summary: A sensitive coating based on Langmuir-Blodgett (LB) films containing monolayers of DPPE with immobilized GOx enzyme was created. The effect of immobilization of GOx enzyme molecules on the surface properties of a Langmuir DPPE monolayer was investigated. The sensory properties of the resulting LB DPPE film with immobilized GOx enzyme in glucose solutions of various concentrations were studied. The findings suggest that acoustic methods can be used to determine the concentration of glucose molecules in an aqueous solution, and the developed technology has potential applications in the food and pharmaceutical industries.

Summary: Molecular self-assembly is the process in which functional assemblies of different structural components are formed through weak and reversible non-covalent interactions based on molecular recognition. In this study, two special amphiphilic molecules, indocyanine green (ICG) and its derivative (CCS), were combined with two dye molecules for self-assembly using the Langmuir-Blodgett (LB) technique. The ordered LB films showed better optoelectronic properties and hydrophobicity compared to drop-casting films, indicating their potential application in optoelectronic functional ultrathin film devices.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.
