Visualizing molecular motion of substituted 9-phosphaanthracene

Anthracene is a solid organic compound derived from coal-tar distillation. Apart from its use as a red dye, it has also been used in the field of nanographene material design, as it exhibits excellent electronic and light-emitting properties. One of its derivatives, called 9-phosphaanthracene, has been widely studied for decades due to its radical reactivity. This activity grants 9-phosphaanthracenes attractive chemical properties such as eco-friendly redox activity, bioactivity, and combustibility.
