摘要

蒽荧光团和恶嗪发色团在相同的分子结构中偶联,产生基于分子机器的受体1。在TFA处理下,恶嗪闭合形式与1,3,3 -三甲基林多啉结合而打开。这种分子变化产生了140nm的直接从紫外到可见光区域的色移,并伴有强烈的粉红色。这种分子可以用作分子墨水,在纸上打印出不同颜色的装饰。在加入TEA后,感受器的彩色开放形式恢复到原来的无色形式,以摩擦印刷印痕。因此,简单的纸张可以多次使用,以实现写-读-擦除策略。这种可光开关的分子基序可以在印刷和大量纸张消耗的工业中发展出许多机会。

Anthracene-Oxazine based reversible ink
Anthracene fluorophore and an oxazine chromophore get coupled within the same molecular configuration to produce a molecular machine based receptor 1. On treatment with TFA, the oxazine closed form gets open in conjugation with the 1, 3, 3-Trimethylindoline species. This molecular change produces a bathochromic shift of 140nm directly from UV to Visible region in association with intense pink color. This molecule can be used as molecular ink to print a different colored decoration on paper. Upon addition with TEA, the colored open forms of the receptor revert to its original colorless form to rub the printed impression. Thus, the simple paper can be used for multiple times to achieve the write-read-erase strategy. This photoswitchable molecular motif can evolve many opportunities in the industry for printing purpose and huge paper consumption.
