| Abstract: | New metallo-supramolecular nanocellulosic derivatives were prepared by surface modification of cellulose nanocrystals with 4-chloro-2,2′:6′,2″-terpyridine and subsequent coupling with other terpyridine-functionalized derivatives via RuIII/RuII reduction. The terpyridine-modified cellulose nanocrystals (CTP) were characterized using transmission electron microscopy (TEM), magic angle spinning 13C nuclear magnetic resonance (MAS-13C NMR), elemental analysis, as well as Fourier transform infrared (FTIR) and UV-Visible spectroscopy. Metallo-CTP with different optical properties, and expected magnetic and catalytic properties, were easily obtained upon reaction of the prepared CTP with different di- and trivalent transition metal ions (Fe+2, Mn+2, Co+2, and Ru+3). Metallo-supramolecular nanocellulosic derivatives with different properties were prepared by subsequent coupling of RuIII-CTP complex with other terpyridine ligands bearing different functionalities. |
