Autonomous viscosity oscillation by reversible complex formation of terpyridine-terminated poly(ethylene glycol) in the BZ reaction

Abstract

Autonomous viscosity oscillation by the reversible complex formation of terpyridine-terminated PEG and/or terpyridine-terminated TetraPEG in the BZ reaction was achieved. The BZ reaction induces the periodical binding/dissociation of the Ru–terpyridine complex and causes periodical molecular changes to result in viscosity changes.
