Wenhui Niu studied polymer engineering at Sichuan University and obtained her Bachelor’s degree in 2016. From 2016, she started her PhD in chemistry from Shanghai Jiao Tong University under the supervision of Prof. Yiyong Mai. Between 2017 and 2020, she joined Prof. Xinliang Feng’s group as an exchanged PhD student. During her PhD, she worked with the bandgap engineering of graphene nanoribbons with excellent liquid-phase dispersibility. In 2021, she received her PhD degree and joined the group of Prof. Xinliang Feng and continued her academic research as a postdoctoral fellow at Technische Universität Dresden for one year. In 2022, she joined the Max Planck Institute in Halle, where she focuses on the exploitation of novel chiral nanographenes with excellent luminescent properties and chiroptical properties.

Main Research Interests

Our research interests lie in the construction of chiral nanographenes with high-strained structures and high-order helicenes. We are particularly interested in developing the novel strategies to achieve chiral nanographenes with good selectivity and efficiency. With well equipped lab condition, we are able to realize the chiroptical characterizations in our own group, allowing us to further build up the relationship between the structure and property. In addition, we are interested in dissymmetric factor engineering by helicene regulation, which facilitates the amplification of dissymmetric factor. Taking advantage of such chiral materials, we are fascinated to discovery their potential in chiral induced spin selectivity effect and circularly polarized luminescence (CPL) related technologies, for example, CPL emitter.
