At the interface between organic radicals and TiO2(110) single crystals: electronic structure and paramagnetic character

We find that in a paramagnetic pyrene derivative of the nitronyl nitroxide radical deposited on rutile TiO2(110) single crystals the molecules keep/lose their paramagnetic character depending on the local substrate hydroxylation. The first molecular layer may act as a buffer on which intact organic magnets are grown.
