The Novo Nordisk Foundation Center for Protein Design at the University of Copenhagen seeks to appoint two new group leaders in de novo protein design from 1 February 2027 or as soon as possible thereafter. These positions will be at the Assistant or Associate Professor level and associated with the Department of Biology (Faculty of Science) or the Department of Drug Design and Pharmacology (Faculty of Health and Medical Sciences).

Singlet oxygen (1O2) is a highly reactive species central to applications ranging from materials science to photodynamic therapy, yet its detection and controlled handling remain challenging. Herein, we report two new 4a,5a-dihydroazuleno[2,1,8-ija]azulene derivatives, T-AA-F and K-AA-F, uniquely integrate photosensitization, 1O2 capture, storage, and release within a single small-molecule scaffold. Upon UV or visible light irradiation, both compounds generate 1O2 and undergo a selective [4 + 2] cycloaddition at the fused furan unit to form stable endoperoxides exhibiting red emission. Prolonged irradiation using UV (365 nm) or visible light (525 nm) triggers a ring-opening reaction, regenerates the ketone derivatives while releasing 1O2, as confirmed by EPR spectroscopy using TEMP as a trapping agent. The endoperoxides display high thermal stability up to 90 °C, enabling robust 1O2 storage. This fully integrated molecular system represents a rare example of a single-component platform capable of producing, trapping, storing, and releasing 1O2, offering promising opportunities for sensing and bioimaging applications.
