Persistent Bidirectional Optical Switching in the 2D High-Spin Polymer {[Fe(bbtr)<sub>3</sub>](BF<sub>4</sub>)<sub>2</sub>}<sub>ā</sub>
In the covalently linked 2D coordination network {[FeĀ(bbtr)<sub>3</sub>]Ā(BF<sub>4</sub>)<sub>2</sub>}<sub>ā</sub>, bbtr =
1,4-diĀ(1,2,3-triazol-1-yl)Ābutane, the ironĀ(II) centers stay in the
high-spin (HS) state down to 10 K. They can, however, be quantitatively
converted to the low-spin (LS) state by irradiating into the near-IR
spin allowed <sup>5</sup>dd band and back again by irradiating into
the visible <sup>1</sup>dd band. The compound shows true light-induced
bistability below 100 K, thus, having the potential for persistent
bidirectional optical switching at elevated temperatures
