Shape-persistent, truxene-based, nano-sized bisterpyridine ruthenium(ii) complexes: Synthesis and photophysical properties^a

(Figure Presented) A new series of shape-persistent metallomacromolecules G0 and G1 as well as corresponding ligands, based on thiophene-functionalized bisterpyridine-Ru(II) with truxene moieties, as the nodes, were developed. All new compounds were fully characterized by ¹H, COSY, and ¹³C NMR, as well as MALDI-TOF MS. Their photophysical properties revealed that the branched scaffold resulted in high molar absorption coefficients and broad absorption making these materials potential candidates for light-harvesting.
