Ph.D. Position in Polymer Chemistry (Main-Group Polymerisation Catalysis)

About the Project

The group:

The Plajer group works at the interface of main-group chemistry and polymer chemistry, with a strong focus on polymerisation catalysis and polymer microstructure–property relationships. The project is embedded in one of Germany’s strongest polymer research environments, Bayreuth, with close links to polymer physics, materials science, and engineering through the Bavarian Polymer Institute

Current projects centre on the incorporation of main-group elements (e.g. S, Se, P) into polymer backbones using catalytic ring-opening polymerisation methodologies. We combine synthetic inorganic chemistry (catalyst and monomer synthesis) with polymer synthesis, mechanistic analysis, and materials characterisation. A recurring theme is how the chemistry of main-group elements enables controlled degradation, chemical recyclability, metal coordination, and unusual thermal or mechanical behaviour. Students in the group typically work with glovebox/Schlenk techniques, SEC, DSC, TGA, NMR, and mechanical testing, and interact closely with polymer physicists and materials scientists on campus.

The offer:

The Ph.D. project focuses on the synthesis of sulphur- and phosphorus-containing polymers via catalytic ring-opening polymerisation. Key aspects include:

• Synthesis of new monomers, main-group-compatible catalysts and polymerisations under inert conditions
• Mechanistic studies on polymerisation and depolymerisation pathways
• Correlating polymer microstructure with recyclability and metal-binding properties
• Materials characterisation (molar mass, thermal and mechanical properties)

Selected materials will be explored for metal scavenging and coordination, for example in water purification or polymer–metal composite systems in optoelectronics. The exact balance between catalyst development, polymer synthesis, and materials work can be adapted to the background and interests of the candidate.

Conditions and Environment:

The position is fully funded (TV-L E13 50%, starting date flexible) for up to four years. The candidate will benefit from the strong polymer research environment in Bayreuth, access to central characterisation facilities, and opportunities for collaboration, conferences, and international research stays.

Application:

Applicants should have a strong background in synthetic chemistry, preferably in polymer chemistry, inorganic chemistry, or related areas. Experience with air- and moisture-sensitive chemistry is highly desirable. Prior exposure to polymer characterisation or catalysis is an advantage but not mandatory. Applicants should hold, or be close to completing, an M.Sc. (or equivalent) in Chemistry.
