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.6 p.application/pdfeng(c) Wiley-VCH, 2017FluorescènciaFotoquímicaPropietats magnètiquesFluorescencePhotochemistryMagnetic propertiesinfo:eu-repo/semantics/article6744712020-03-25info:eu-repo/semantics/openAccess
