Abstract :
A series of photomagnetic coordination polymer core-shell heterostructures, based on the light-switchable RbaCob[Fe(CN)6]c*mH2O (RbCoFe-PBA) as core with the isostructural KjNik[Cr(CN)6]l*nH2O (KNiCr-PBA) as shell, are studied using temperature-dependent powder X-ray diffraction and SQUID magnetometry. The core RbCoFe-PBA exhibits a charge transfer-induced spin transition (CTIST), which can be thermally and optically induced. The ability to tune the rate of optically induced magnetic and structural phase transitions through control of mesoscale architecture presents a new approach to the development of photoswitchable materials with tailored properties.
