Abstract

A novel 1-dimensional spin-crossover complex {[Fe(MPEG-trz)3](BF4)2} where polymer chain is attached by chemical modification has  already been successively synthesized by self-assembly reaction between methoxy polyethylene glycol (MPEG) grafted 4-amino-1,2,4-triazole (MPEG-trz) and Fe(BF4)2·6H2O. The structure information could be obtained through FT-IR, XRD and 1H NMR measurements, while spin-crossover behaviour of complex is inspected by super-conducting quantum interference device (SQUID) and DSC. The new metalloorganic polymer not only shows mechanical behaviour particularly the malleability of the material but also exhibit an abrupt spin crossover behaviour with a slender hysteresis loop of 1 K.
