Abstract

original image

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 π-stacking interactions. The metallo-intercalator complex Ru(dppz)(phen)22+ binds to the helical polymer via intercalation and the complex is highly luminescent when it is bound to the polymer (see Figure).
