Difluoroboron avobenzone (BF(2)AVB), 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 BF(2)AVB 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.
二氟硼基阿伏苯宗（BF(2)AVB），一种商业防晒霜产品的简单硼络合物，在固态中表现出形态依赖性发射和机械变色发光。当刮擦、涂抹甚至轻轻触摸时，BF(2)AVB 薄膜在紫外光激发下的发射颜色明显红移。在摩擦区域，室温下荧光恢复缓慢，加热时恢复更快，从而产生一种简单的可重写“刮擦表面”油墨，具有潜在的商业用途。
