Ultralong phosphorescence visualization of dynamic behavior in 3D information encryption and circuit heat generation.

Caption

(a) Skin temperature responsive shape deformation to access different information. The information is patterned on the Cor-EP films via a photo mask. Information output I is shown in the programmed 3D shapes and information output II is readable when the 3D shapes are unfolded at surface temperature. (b) Illustration of the function of Cor-EP-Cu as a circuit switch. (c) The repeated switch on-off cycles of Cor-EP-Cu-60 as a circuit switch at 8 V. (d) The photos of afterglow and thermal imaging of Cor-EP-Cu-60 when it functions as a circuit switch at 6, 7 and 8 V. Cor-EP-Cu-60 indicates it is photo-crosslinked for 60 s. Scale bar, 10 mm.
