Abstract:In this study, a series of different generation hyperbranched poly(amine-ester) with hydroxyl as terminal group were synthesized and used as protectants to synthesize gold nanoparticles with a facile and highly reproducible method. The effect of hyperbranched poly (amine-ester) generation on size and their distribution of gold nanopartciels were discussed. The results of ultraviolet visible absorption spectroscopy, Transmission electron microscopy and scanning electron microscopy showed that the mean diameter … Show more
“…Contrary to procedures described in the literature for which HAuCl4 was used as Au precursor, 20 we used AuCl3 whose fast reduction in an aqueous solution of Tetronics®90R4 (0.17 mmol in 5 mL water) led to AuNP at 40 °C. A small sacrificial quantity of Tetronics® acted as reductive agent thanks to terminal hydroxyl groups of Tetronics® 21 and imparted a pink color characteristic of the presence of AuNP to the solution (Supporting Information, Fig. S1).…”

Hydrogenation of alkenes, alkynes and aldehydes was investigated under biphasic conditions using Au nanoparticles (AuNP) embedded into combinations of α-cyclodextrin (α-CD) and a poloxamine (Tetronic®90R4).
