Abstract
Difluoroboron avobenzone (BF2AVB), a simple boron complex of a commercial sunscreen product, exhibits morphology-dependent emission and mechanochromic luminescence in the solid state. When scratched, smeared, or even gently touched, the emission color of BF2AVB films is significantly red-shifted under UV excitation. In the rubbed regions, the fluorescence recovers slowly at room temperature or much faster with heating, resulting in a simple rewritable “scratch the surface” ink of potential commercial use.

Brett A. Beiermann, Sharlotte L.B. Kramer, Jeffrey S. Moore, Scott R. White, and Nancy R. SottosACS Macro Letters2012 1 (1), 163-166The orientation of force-sensitive chemical species (mechanophores) in bulk polymers was measured via the anisotropy of fluorescence polarization. Orientation measurements were utilized to investigate the role of mechanophore alignment on mechanically ...
