This facile interconversion of dinuclear double helicates and side-by-side species: a reprogrammable ligand with potential sensor applications

摘要

The ligand L-1 forms a dinuclear double helicate with Cu+ but upon addition of Ba2+ to the system a side-by-side species is formed both in solution and in the solid state; in the presence of Na+ both the helicate and the side-by-side species are formed in roughly equal amounts in solution.
