摘要：

Difluoroboron avobenzone (BF(2)AVB), a simple boron complex of a commercial sunscreen product, exhibits morphology-dependent emission and mechanochromic the solid state. When scratched. smeared, or even gently touched, the emission color of BF(2)AVB films is significantly red-shifted Under UV excitation. In the rubbed regions, the florescence recovers slowly at room temperature Or much Faster with heating, resulting in a simple rewritable "scratch the surface" ink of potential commercial use.
