Abstract

A bis(pyrazolylpyridyl) ligand, L, containing a cen- tral photochromic dithienylethene spacer predictably forms a ferrous [Fe2L3]4+ helicate exhibiting spin crossover (SCO). In solution, the compound [Fe2L3](ClO4)4 (1) preserves the magnetic properties and is fluorescent. The structure of 1 is photo-switchable following the reversible ring closure/opening of the central dithienylethene via irradiation with UV/visible light. This photoisomerization switches on and off some emission bands of 1 and provides a means of externally manipulating the magnetic properties of the assembly.
