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) 2 2+ binds to the helical polymer via intercalation and the complex is highly luminescent when it is bound to the polymer (see Figure).
