On the History of Reactive Mesogens: Interview with Dirk J. Broer

Abstract

Prof. Dirk Broer is among the pioneers and most active researchers in the field of stimuli-responsive liquid crystal (LC) networks. He is the inventor of reactive mesogens, a class of materials with far-reaching implications in liquid-crystal photonics and in the triumph of LC-based shape-shifting polymers. Together with his team, Prof. Broer continuously produces innovative solutions for controlling and programming new functions into soft responsive materials. Through this Interview, it is our great pleasure to gain insights into his personal views on both the past and the future, and to learn about the historical turns that led to the development of reactive mesogens as well as his vision on where the field is heading.

Keywords: adaptive mechanics; birefringent optics; liquid crystal elastomers; liquid crystal networks; reactive mesogens.
