Abstract
Q-band electron paramagnetic resonance (EPR) data conclusively demonstrate that the iron and cobalt centers in the solid solution [Fe(bpp)2]0.97[Co(terpy)2]0.03[BF4]2 (bpp = 2,6-dipyrazol-1-ylpyridine) undergo allosteric spin-state switching during light-induced excited-spin-state trapping (LIESST) at 20 K and thermal relaxation around 80 K. EPR of [Cu(terpy)2]2+ and [Cu(bpp)2]2+, doped into the same host lattice, also indicates expansion of the copper coordination sphere during LIESST excitation.
