Abstract

Abstract : Platinum(ii )-containing associative metallopolymers can self-assemble into dynamic reversible networks through Pt(ii )⋯Pt(ii ) and/or π–π stacking interactions, providing a rheological protocol to quantify such noncovalent interactions. Abstract : Platinum(ii )-containing associative metallopolymers can self-assemble into dynamic gel networks through Pt(ii )⋯Pt(ii ) and/or π–π stacking interactions. Above the gel–sol transition point, the stress relaxation contributed by the Rouse-type motion of the unentangled polystyrenes ( τ 0 ) and the sticker dissociation of the platinum(ii ) units ( τ s ) can be simultaneously observed over the timescale of linear viscoelasticity, quantifying Pt(ii )⋯Pt(ii ) and/or π–π stacking interactions using the ratio of τ s / τ 0 .
