Abstract

New coordination polymers based on two metal-containing moieties Ru-Ag are synthesized: Na[RuCpX(PTA)-μ-(PTA)-1κP:2κ²N-AgX₂]_∞ (X = Cl (1), Br (2), I (3)). Characterization is performed by NMR, UV-visible and FT-IR spectroscopy, optical-electron microscopy, and elemental analyses (C, H, N, S). Light scattering is employed to characterize the colloidal particles growth by polymer self-assembling. These structures are stable over a broad range of pH and exhibit thermally-driven swelling, thus resembling a typical thermosensitive hydrogel.

Keywords: PTA; light scattering; organometallic; polymer swelling; ruthenium complexes.
