PhD Project: Dyes with Switchable Intersystem Crossing for Photonics

Job Description

DyeSICPhoto project aims develop a conceptually new type of functional dyes with programmable excited state behaviour and to unlock their practical potential in photonics. This will be achieved by optimization of the spin-orbit charge transfer intersystem crossing (SOCT-ISC) process in electron donor-acceptor molecules. In such systems, fluorescence and triplet state quantum yields depend on the charge transfer process and thus can be finely controlled. Dyes will be designed to operate either as bright fluorophores or photosensitizers transferring energy to other molecules, depending on environmental parameters, applied external stimuli, or activating species. In addition to having significant fundamental importance for understanding the photophysics of organic molecules this work will afford advanced molecular systems and materials with high added value for biophotonics and energy conversion. To demonstrate the potential in biophotonics we will use these systems as smart sensitizers for photomedical treatments and imaging probes for reactive oxygen species in living cells. Alternatively, new dyes will be used as components of multichromophoric assemblies capable of efficient light energy harvesting and conversion, for solar cells efficiency enhancement through the process of triplet-triplet annihilation upconversion.
