Investigate light-induced excited spin-state trapping and post-illumination magnetic interactions in a cyanide-bridged heterometallic coordination polymer.
Synthesized and structurally characterized the one-dimensional coordination compound [Fe(L)(CN)2][Mn(hfac)2] comprising repeating -NC-Fe-CN-Mn- units.
Subjected the heterometallic complex to optical illumination to test for light-induced excited spin-state trapping (LIESST) effects and recorded resultant magnetic coupling.
Demonstrated that the 1-D coordination compound exhibits light-induced excited spin-state trapping upon light exposure.
Observed antiferromagnetic coupling between photo-generated high-spin iron(II) (S = 2) and manganese(II) (S = 5/2) ions after illumination.
