From: Dynamic wrinkling pattern exhibiting tunable fluorescence for anticounterfeiting applications
a Chemical structure of P4VP-nBA-S/DSP-OH served as the top layer and the protonation and photoisomerization reaction during the evolution process of winkled and fluorescent pattern. b Schematic illustration of the dual pattern with tunable wrinkle and fluorescence in response to visible light and acid based on (P4VP-nBA-S/DSP-OH)/PDMS bilayer system. c Corresponding laser scanning confocal microscope (LSCM) images of wrinkled surface with fluorescence color responsive to visible light and acid. Scale bar: 100 μm.
