Postdoc Marcel Handke, graduate students Yang Wu and Yuantao Li, and Tony Hu discovered that the ubiquitous luminophore [Ru(bpy)3]2+ can be sequestered as a guest in an unusual guanidinium organosulfonate host framework architecture that guides the [Ru(bpy)3]2+ into 1D zigzag chains that suggest unique through-space energy transfer characteristics.
