Bistricyclic aromatic enes with fast conformational transition for ultrathin piezochromic films†
Abstract
New bistricyclic aromatic enes (BAEs) with a faster conformational transition were synthesized to improve the fabrication efficiency of BAE-based piezochromic films. Through ultrathin design, our 5-μm-thick BAE-based films can conform to non-planar surfaces and minimize disruption to the original interfacial pressure, improving the precision for mapping interfacial pressure distribution.
