Abstract:
Endowing external, remote, and dynamic control to
self-organized superstructures with tailored functionalities is a principal
driving force in the bottom-up nanofabrication of molecular devices.
Light-driven chiral molecular switches or motors in liquid crystal (LC) media
capable of self-organizing into optically tunable one-dimensional (1D) and
three dimensional (3D) superstructures represent such an elegant system.
However, employing near infrared (NIR) light would be much more desirable than
either ultraviolet or visible light in the fields such as life science,
materials science, and aerospace due to its superior penetration and
invisibility for temporal and spatial remote activation of materials with
relatively low interference and high precision. In this talk, I will focus on
our recent research and development on the NIR-responsive molecular switches
and their applications for triggering chiral liquid crystal superstructures:
from 1D to 3D.
Biography:
Ling Wang is currently a postdoctoral research associate in
the group of Prof. Quan Li at the Liquid Crystal Institute from Kent State
University. He received his Ph.D. in the Department of Materials Physics &
Chemistry from University of Science and Technology Beijing (2013), and then he
worked as a research associate in the Department of Materials Science &
Engineering from Peking University. Together with his advisor Prof. Huai Yang.
His research focuses on the synthesis, properties and applications of liquid
crystal materials, stimuli-responsive molecular switches, and novel functional
nanomaterials.
