Postdoc in Molecular Solar Thermal Energy Storage and Supramolecular Materials

Can sunlight be stored in molecules and released as heat when needed? We are seeking a postdoctoral researcher to develop supramolecular materials combining molecular solar thermal (MOST) energy storage with light-controlled phase transitions, using synthetic chemistry, photochemistry and automated discovery. About us You will join the research group of Professor Kasper Moth-Poulsen in the Division of Chemistry and Biochemistry, Department of Chemistry and Chemical Engineering, at Chalmers University of Technology in Gothenburg, Sweden. Our interdisciplinary research uses synthetic chemistry to address challenges in solar-energy storage, functional molecular materials and energy conversion. The group has extensive experience in molecular photoswitches for solar energy storage, so-called MOST systems, and automated experimental approaches. You will work in an international, collaborative research environment at the interface of organic chemistry, supramolecular chemistry, photochemistry and materials science. Group website: www.moth-poulsen.com About the research project MOST systems use photoactive molecules to capture and store solar energy through reversible photochemical transformations. The stored energy can subsequently be released as heat on demand. The central ambition of this project is to combine molecular photoswitching with cooperative intermolecular interactions and phase behavior to develop a new family of functional materials for thermal-energy storage. You will investigate relationships between molecular structure, supramolecular organization, photochemical performance, phase transitions, energy density and cycling stability. A second key component is automated materials discovery. You will develop and apply automated synthesis, screening and characterization workflows to explore a broader design space, identify promising materials more efficiently, and generate deeper mechanistic insight into their function.

DOI Who we are looking for The following requirements are mandatory:

• A doctoral degree in chemistry, materials science, chemical engineering or an equivalent foreign degree. This eligibility requirement must be met no later than the time the employment decision is made.
• Strong written and verbal communication skills in English
• Documented hands-on research experience in synthetic chemistry.

You are expected to be somewhat accustomed to teaching, and to demonstrate good potential within research and education. The following experience will strengthen your application:

• It is highly meritorious if the doctoral degree has been obtained within the last three years prior to the application deadline
• Experience in organic synthesis of molecular photoswitches, photochromic compounds or molecular solar thermal energy-storage systems.
• Experience in thermal and materials characterization, for example differential scanning calorimetry (DSC), microscopy or diffraction techniques
• Experience in Automation, high-throughput experimentation, flow chemistry, laboratory robotics, programming or data-driven materials discovery

We welcome applicants with complementary strengths across these areas; prior experience in every technique is not expected. Scientific curiosity, experimental creativity and a collaborative working style are important. What you will do

• Design and synthesize photoswitchable molecules and supramolecular materials for coupled MOST and phase-change energy storage.
• Investigate photochemical switching, thermal energy storage and release, solid–liquid transitions, and reversible cycling.
• Explore structure–property relationships, including the influence of molecular packing and supramolecular interactions on energy density, kinetics and stability.
• Develop, automated experimental workflows for materials synthesis, screening, data collection and analysis.
• Supervise master’s and/or PhD students to a certain extent
• Possibility to engage in teaching at undergraduate/master’s level

The position is meritorious for future roles in academia, industry, or the public sector. Contract terms The position is a temporary full-time employment for two years. The position requires physical presence throughout the entire employment. A valid residence permit must be presented by the start date, otherwise the offer may be withdrawn. What we offer
