本工作基于前期基礎，研究一種側鏈含有Ru(II)(Tpy)2功能基團的水凝膠的制備方法，可逆的響應性，以及BZ反應在凝膠體系中的發生情況。
This work aims at developing an approach to Ru(II)(Tpy)2-functionalized hydrogels and exploring the couplingof 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.
