As a result of their optical and redox properties, bipyridyl (bpy) and terpyridyl (tpy) ruthenium complexes play vital roles in numerous domains. Herein, the design and synthesis of two bipyridyl and terpyridyl ruthenium(II) building units and are explained. A [Ru(bpy) ] functionalized triangle and a Sierpiński triangle were synthesized in almost quantitative yields by the self-assembly of with Zn ions and by the heteroleptic self-assembly of and with Zn ions, respectively. The Sierpiński triangle contains the coordination metals [Ru(bpy) ] , [Ru(tpy) ] , and [Zn(tpy) ] . According to research on the catalytic activity of amine oxidation on supramolecules and , the benzylamine substrates were nearly entirely transformed to -benzylidenebenzylamine derivatives after 1 h under a Xe lamp. Furthermore, the observed ruthenium-containing terpyridyl supramolecule maintains high luminous performance at ambient temperature. This discovery opens up new possibilities for the rational molecular design of terpyridyl ruthenium fluorescent materials and catalytic functional materials.
