Dynamic metallopolymer networks: a protocol to quantify Pt(ii)MIDLINE HORIZONTAL ELLIPSISPt(ii) and pi-pi stacking interactions

Platinum(ii)-containing associative metallopolymers can self-assemble into dynamic gel networks through Pt(ii)MIDLINE HORIZONTAL ELLIPSISPt(ii) and/or pi-pi stacking interactions. Above the gel-sol transition point, the stress relaxation contributed by the Rouse-type motion of the unentangled polystyrenes (tau(0)) and the sticker dissociation of the platinum(ii) units (tau(s)) can be simultaneously observed over the timescale of linear viscoelasticity, quantifying Pt(ii)MIDLINE HORIZONTAL ELLIPSISPt(ii) and/or pi-pi stacking interactions using the ratio of tau(s)/tau(0).
