Synthesis and characterization of novel coordination spin crossover poly(glycidyl methacrylate) with pendant iron(II)-4-amino-1,2,4-triazole groups

Poly(glycidyl methacrylate) (PGMA) with pendant iron(II)-triazoles groups was synthesized through the grafting method. The structure was characterized by 1H NMR, FTIR and XRD. Meanwhile, SQUID and DSC were conducted to measure the spin crossover property of the composite. The Fe(II) complexes modified by PGMA not only display an evident spin crossover performance, but also have excellent processability.
