Sigurd Höger

Prof. Dr. Sigurd Höger is Professor of Organic Chemistry at the Kekulé-Institut at the University of Bonn. His research explores the synthesis and characterization of advanced organic materials with applications in electronics, photonics, and antimicrobial technologies.

Research focuses include:

• π-Conjugated oligomers and polymers
• Molecular spoked wheels and macrocycles
• Ladder polymer architectures
• Functional coatings with antimicrobial properties

Höger's publications showcase innovations in molecular design, including nanoscale conjugated ladders for optoelectronics and supramolecular nanopatterns for surface functionalization. His group combines synthetic chemistry with advanced characterization to develop materials for organic light-emitting diodes, solar cells, and bioactive surfaces.
