Two anthracene-based derivatives, having one or two acylhydrazone branches attached on the anthracene, namely, asymmetrical AHP-1 and symmetrical AHBP-1 were designed. These compounds exhibited mechanofluorochromic behavior with the emission colors reversibly changing upon grinding and recrystallizing. The mechanofluorochromic mechanism was explored and ascribed to the crystalline-amorphous phase transformation. In addition, the red-shifted extent of fluorescent emission of the ground AHBP-1 samples was more than that of AHP-1.

蒽基酰基hydr衍生物的机械荧光色行为

设计了两种蒽基衍生物，它们具有一个或两个连接在蒽上的酰基ac分支，即不对称的AHP-1和对称的AHBP-1。这些化合物表现出机械氟致变色行为，其发射颜色在研磨和重结晶时可逆地变化。探索了机械荧光致变色机理，并将其归因于结晶-非晶相变。此外，地面AHBP-1样品的荧光发射红移程度大于AHP-1。
