Research project description and main objectives: One main issue of the POLYTHEA project is to develop photosensitizing dyes which can be used in a modular fashion for a variety of biomedical applications within the consortium. There are multiple advantages in using NIR light for activating photophysical processes relevant for photodynamic therapies.

Thus, this project will focus on the development of new systems than can be excited with NIR light by combining NIR dyes such as cyanines with porphyrins in order to produce reactive oxygen species. Using (photoinduced) charges that can recombine onto local triplet states to generate reactive oxygen species (also with functionalized surfaces) will be adressed.

This project is divided into two parts:

1)      Synthesis of PS with targeted photophysical properties.
2)      Evaluation of these properties
