Conjugation of a Silver-Based Coordination Polymer with Curcumin: A New Case of an Inorganic Polymeric Co-crystal

Abstract: A new structural form of the already reported silverbased 1D coordination polymer (CP) [(bpy)Ag (OTf)] ∞ (bpy = 2,2′-bipyridine; OTf = trifluoromethanesulfonate) has been synthesized and fully characterized through single-crystal and powder XRD, DSC, and FTIR analysis. The reaction of both structural forms of the Ag(I) CP with curcumin (curc) afforded the formation of a new solid form, specifically an inorganic polymeric co-crystal between curc and [(bpy)Ag (OTf)] in a 1: 4 molar ratio, respectively. The co-cr… Show more

“…In particular, the curc-EC sample is characterized by the absence of the curc melting transition (see ref. [25] for the DSC curves of the additives), indicating a good miscibility between the polymer and the polyphenol, as already revealed by PXRD analysis. Moreover, within the DSC trace of curc-EC, the T g occurs at a temperature five degrees lower than that of EC-0, pointing out a slight plasticizing effect exerted by curc on EC matrix.…”

“…[25] The same applies when these Ag(I) polymers are mixed with EC powder in the solid state. [25] On this basis, the presence of the EC polymer in the dichloromethane solution seems be responsible for the transformation of the Ag(I) polymers into a discrete compound. Being the Ag α À EC and Ag β À EC undistinguishable, hereafter they will be referred to as AgÀ EC.…”
