Tuning of molecular qubits: very long coherence and spin-lattice relaxation times.

K Bader1, M Winkler1, J van Slageren2.   

Abstract

We report a pulsed EPR study on different transition metal phthalocyanines, elucidating the dependence of spin relaxation on solvent, ligand and metal ion. Coherence times of >40 µs and spin-lattice relaxation times of up to 2 s were found. Minimization of SOMO-environment overlap leads to increased coherence times.
