Soft matter with a hard core: Through PtII⋅⋅⋅PtII and hydrophobic interactions, planar organoplatinum(II) cations with chloride or sulfate as counterions self-organize themselves in water into red-emissive, chromonic, and viscoelastic mesophases from which aligned films and discrete uniaxial microfibers with cofacial molecular orientations can be readily prepared.
