In control: Multicomponent stereoisomeric assemblies have been synthesized from asymmetric cyclometalated platinum corner units that have exchangeable cis coordination sites with different labilities. A template-free, kinetically controlled approach resulted in the selective formation of trigonal prismatic isomers by changing the sequence of addition of 4,4'-bipyridine (red) and tris(4-pyridyl)triazine (green) to [(LPt)2Cl2] (blue and yellow; HL = 2-phenylpyridine).

A series of triangular metallaprisms with a kinetically inert Pt-N bond have been synthesized from the stepwise assembly of a Pt-corner, linear linker 4,4′-bipy (4,4′-bipy = 4,4′-bipyridine) and triangular ligand [tpb or tpt, tpb = tris(4-pyridyl)benzene, tpt = tris(4-pyridyl)triazine]. The use of an unsymmetrical [Pt(HL)]-corner (H2L = 2,6-diphenylpyridine) leads to novel isostructural products. Phenyl rotation at the metal-corners endows these complexes with good aggregation-induced emission (AIE) function, with varied activities across the isostructural complexes. The coordination sequence of electron-deficient ligand tpt also imparts significant influence on the complex emission. These organoplatinum triangular metallaprisms thus provide a good model to study the influence of building blocks and coordination sequence on the luminescence of supramolecules.
