Shape-Persistent, Truxene-Based, Nano-Sized Bisterpyridine Ruthenium(II) Complexes: Synthesis and Photophysical Properties
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 H-1, COSY, and C-13 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.
