Dynamic wrinkling pattern exhibiting tunable fluorescence for anticounterfeiting applications

T. Ma, T. Li, et al.

This paper showcases a groundbreaking supramolecular network that enables dynamic dual patterning in bilayer wrinkling systems, where both wrinkle morphology and fluorescence can be adjusted using visible light or acids. The innovative surface can switch between smooth and wrinkled states, with fluorescence changing from blue to orange-red. Conducted by Tianjiao Ma, Tiantian Li, Liangwei Zhou, Xiaodong Ma, Jie Yin, and Xuesong Jiang, this research highlights potential anticounterfeiting applications.

Abstract

This paper demonstrates a dynamic dual pattern using a supramolecular network for bilayer wrinkling systems. Both wrinkle morphology and fluorescence color are simultaneously regulated by visible light-triggered isomerization or acids. The resulting hierarchical patterned surface reversibly changes between smooth and wrinkled states, with fluorescence shifting from blue to orange-red. This smart surface with dynamic hierarchical wrinkles and fluorescence has potential anticounterfeiting applications.
