Solvent-induced self-assembly of a meta-linked conjugated polyelectrolyte. Helix formation, guest intercalation, and amplified quenching
A water-soluble meta-linked poly(phenylene ethynylene) is shown to fold into a helical conformation in water. The helix is stabilized by solvophobic forces and n-stacking interactions. The metallo-intercalator complex Ru(dppz)(phen)(2)(2+) binds to the helical polymer via intercalation and the complex is highly luminescent when it is bound to the polymer (see Figure).
