Johan Liotier

Dr. Johan Liotier is a Postdoctoral Researcher at the Cluster of Excellence livMatS (Freiburg Center for Interactive Materials and Bioinspired Technologies) at the University of Freiburg. His research focuses on synthesizing small molecules capable of functionalizing and crosslinking non-functional polymers via C,H-insertion chemistry. These molecules enable the creation of stimuli-responsive 3D networks using orthogonal triggers like light and temperature, with applications in reversible crosslinking through cleavable moieties. His primary supervisor is Prof. Dr. Jürgen Rühe.

Key research areas include polymer functionalization, photochromic materials, photovoltaic systems, and sustainable materials upcycling. He has contributed to advancements in dye-sensitized solar cells and photochromic dyes, with a focus on optimizing optoelectronic properties and dynamic optical control. His work bridges organic chemistry, materials science, and energy technologies, emphasizing practical applications in adaptive materials and renewable energy systems.
