About this position
The PhD project is based in the Crespi group at Uppsala University’s Department of Chemistry – Ångström Laboratory, a large chemistry environment with strong internationally oriented research and education activities. The work focuses on phosphorus-based photoswitches and the project “Hemiphosphaindigos: New Gears for Molecular Machines”, funded by the Swedish Research Council.
The successful candidate will work on the design and synthesis of new phosphorus-containing indigoid chromophores and study how phosphorus functionalization changes their light-driven structural behavior. A major part of the project is to connect molecular structure with isomerization efficiency and stability, using organic synthesis, purification, structural characterization, and photochemical analysis. The experimental program includes NMR spectroscopy, mass spectrometry, UV-Vis spectroscopy, irradiation studies, photostationary-state analysis, quantum-yield measurements, and thermal kinetics.
As the project develops, the student will also contribute to studies of directional molecular motion and the effects of supramolecular confinement on photochemistry. The research is integrated with advanced time-resolved spectroscopy and computational chemistry through expertise in the group and international collaborations, offering training in complementary methods. The position also includes doctoral coursework and dissemination of results through publication and presentation.
The department states that teaching may be included according to departmental arrangements, and the appointment is a full-time doctoral position in Uppsala.
Funding details
Swedish Research Council-funded PhD project; full-time doctoral employment at 100%.
What's required
Applicants must have a second-cycle degree in chemistry or a closely related discipline, or at least 240 higher-education credits including at least 60 credits at Master’s level with an independent project of at least 15 credits, or equivalent knowledge obtained in Sweden or abroad. Very good oral and written English is required. The candidate should have practical experience in organic synthesis, purification and structural characterization from a degree project or research project, and be able to plan, document, and interpret laboratory experiments carefully and safely. Collaborative skills, drive, independence, and complementary experience relevant to the department’s research are considered. Experience in organophosphorus or other main-group chemistry, photochemistry or photochromism, UV-Vis or NMR spectroscopy, reaction kinetics, supramolecular chemistry, photosensitive or chiral molecules, or quantum-chemical calculations is advantageous.
How to apply
Submit an application through the Varbi portal. Include a cover letter describing your motivation and relevant laboratory experience, a CV, degree certificates and transcripts, a Master’s thesis or equivalent written research work, and contact details for two referees.
