On June 11, 2026, Researcher Xu Gang from the Fujian Institute of Research on the Structure of Matter, and Researcher Feng Liang from the Dalian Institute of Chemical Physics, both affiliations of the Chinese Academy of Sciences, were invited to visit the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University, and presented reports titled “Conductive MOF Films and Their Gas-Sensitive Properties” and “Research on Interfacial Regulation and Multimodal Signal Conversion in Film-Based Chemical Sensors”, respectively.

Xu Gang introduced the “interface-confined assembly” strategy developed by his team, in which they overcame the challenge of producing high-quality MOF films through a series of novel film fabrication methods, and conducted fundamental research on the application of MOF film materials in chemical resistance gas sensors.

Feng Liang elaborated on multi-scale control strategies, including molecular diffusion kinetics, interfacial functionalization, band structure defect engineering, and atomic-scale built-in electric fields. He analyzed the key roles these strategies play in accelerating interfacial molecular diffusion, suppressing fluorescence quenching, and optimizing semiconductor band structures, thereby revealing the microscopic mechanisms underlying the efficient conversion of chemical information into multimodal optical and electrical signals.

The sessions were moderated by INCSMM vice dean Prof. Ding Liping, and attended by more than 50 faculty members and students from the institute, who engaged in discussions with the two presenters.
