Abstract
We present spectroscopic measurements looking for the coherent coupling between molecular magnetic centers and microwave photons. The aim is to find the optimal conditions and the best molecular features to achieve the quantum strong coupling regime, for which coherent dynamics of hybrid photon-spin states take place. To this end, we used a high critical temperature YBCO superconducting planar resonator working at 7.7 GHz and at low temperatures to investigate three molecular mononuclear coordination compounds, namely (PPh4)2[Cu(mnt)2] (where mnt2- = maleonitriledithiolate), [ErPc2]-TBA+ (where pc2- is the phtalocyaninato and TBA+ is the tetra-n-butylammonium cation) and Dy(trensal) (where H3trensal = 2,2',2''-tris(salicylideneimino)triethylamine). Although the strong coupling regime was not achieved in these preliminary experiments, the results provided several hints on how to design molecular magnetic centers to be integrated into hybrid quantum circuits.

Summary
In the last years we have been exploring the possibility to coherently manipulate molecular magnetic moments (hereafter referred as “molecular spins” for simplicity). In this work we present preliminary circuit-QED experiments to test the magnetic coupling between selected molecular spin ensembles and a superconducting YBCO coplanar resonator. The transmission spectra measured for θ=0° show the shift of the main resonance toward lower gfactors, as it is expected from the easy plane anisotropy of the [ErPc2]-TBA+ molecule (Figure S4 of the ESI).
