On July 29, 2026, Prof. Wang Dongsheng from University of Electronic Science and Technology of China was invited to visit the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University, where he presented a report titled “Self-adaptive Photochromism”.

In the report, Prof. Wang proposed that, unlike traditional “active camouflage” solutions that rely on electronic devices, adaptive photochromic materials utilize their own physicochemical properties to spontaneously change color in response to the surrounding environment, offering the unique advantages of requiring no additional power supply and being able to be applied directly as a coating on the surfaces of various substrates, and demonstrating broad application potential in fields such as military camouflage, smart protection, and civilian decoration.

Focusing on the technical framework of “Innovation in Fundamental Principles—Development of Material Systems—Expansion of Application Scenarios”, Prof. Wang presented his team’s latest breakthroughs in the field of multifunctional photosensitive materials and devices based on donor-acceptor staigomers (DASAs). He elaborated on the team’s optimizations in terms of light response speed, color-change stability, and environmental adaptability, and shared the team’s research progress in developing multi-environment adaptive camouflage scenarios for applications such as clothing, tents, and vehicles, demonstrating the path for this technology to transition from the laboratory to industrial applications.

During the Q&A session, Prof. Wang discussed with faculty and students in attendance on topics such as the molecular design of adaptive photochromic materials, the environmental adaptability of coatings, and their interdisciplinary applications in sensing and camouflage, and answered their questions.

The session was moderated by Prof. Ma Jiani, and attended by more than 30 faculty members and students from the institute and the School of Chemistry and Chemical Engineering.
