1D anionic dysprosium( iii ) coordination polymers with photoactive protonated 4-styrylpyridinium counter-ions: photoinduced modulation of magnetic behavior via synergistic dual photoresponses

Substituent-directed synergistic control of photocycloaddition and radical generation enables programmable optical modulation of single-molecule magnet behavior in a series of dysprosium( iii ) complexes.
