Unique Piezochromic Fluorescence Behavior of Dicyanodistyrylbenzene Based Donor–Acceptor–Donor Triad: Mechanically Controlled Photo-Induced Electron Transfer (eT) in Molecular Assemblies (Adv. Mater. 40/2012)
图评:手指点击产生奇幻的效果,是科幻片中常见的一种镜头语言。从心里来讲,人类对自己的力量充满了期望,用自己手指触摸奇幻是人类不断在做的梦。让人产生梦幻的画面总是人最想去看的,能让人产生奇幻的文章,也会让人忍不住去看看这位科学家究竟做了什么样奇幻的事情。
科学不是空想,不是标题党,但是科学可以有奇幻,可以有吸引力。
A donor–acceptor–donor triad, which exhibits fluorescence on-off switching with high contrast ratio (ca. 1000) in response to mechanical stimulus in the solid state, is reported by Soo Young Park and co-workers on page 5487. This system provides a very unique example of high contrast fluorescence switching that is driven by a mechanical force controlled photo-induced electron transfer (eT) in molecular assemblies.
