This work aims at developing an approach to Ru(II)(Tpy)2-functionalized hydrogels and exploring the coupling of the hydrogels with the Belousov-Zhabotinsky (BZ) reaction. Based on free radical polymerization, two synthetic routes are developed. The first one is the direct gelation by copolymerization of acrylamide as hydrophilic component and Ru(II)(Tpy)2 as the functional group. The second one is carried out through a combined approach. A terpyridine-containing hydrogel is first prepared and then post-functionalized by coordination between Ru(III)(Tpy)Cl3 and terpyridine groups in the hydrogel network. Utilizing the synthetic hydrogels, the reversible redox responsiveness, the coupling with the BZ reaction, the occurrence and the self-oscillating properties of the BZ reaction in the hydrogel networks are studied.
