Helmut Ringsdorf

Ringsdorf was born in Gießen, People's State of Hesse in 1929.[2][3]

Ringsdorf died on 20 March 2023, at the age of 93.[4]

Ringsdorf took undergraduate studies in Chemistry, Politics and Geology at the universities at Frankfurt, Darmstadt and Freiburg.[2][3]

In 1956, Ringsdorf wrote his master's thesis under Hermann Staudinger and, in 1958, wrote his doctoral dissertation under Staudinger and Elfriede Husemann. He was Staudinger's last student.[5]

Field of Expertise & Research Interests: Polymer Science as a Bridge between Material Science and Life Science.

Molecular Architecture and Functionalization of Polymeric Liquid Crystals: Synthesis, structure and property of liquid crystalline side group and main chain polymers; variation of the type of mesogens (rods, discs, boards) and variation of phases. Dye containing and photoreactive liquid crystalline polymers for reversible information storage and non linear optic materials. Phase induction and phase variation of liquid crystalline systems via Charge-Transfer-interaction and metal complexation. Photoconductive discotic systems.

Synthesis, Structure and Properties of Functional Supramolecular Systems: Polymerizable and functional amphiphiles (detergents, lipids), polymeric monolayers and multilayers via the Langmuir-Blodgett technique and via self-assembly on various surfaces. Liposomes, Black Lipid Membranes, mobile supported bilayers, H-bond induced band structures in water, organization and recognition induced functionality. Multicompartment polymer micelles.

Attempts to Mimic Biomembrane Processes: Synthetic and natural receptors in molecular assemblies; molecular recognition, 2D-crystallization and function of proteins on monolayers and liposomes, e.g. lectins, streptavidin, monoclonal antibodies, phospholipase A2 and acetylcholinesterase, tailoring of bioreactive surfaces; mixed protein multilayers. Protein–DNA-interaction at ligand lipid monolayers.

Polymers as Active Agents in the Medical Field: Polymer Therapeutics, Polymer radiation prophylactics, polymeric antitumour agents on a molecular and a cellular level.
