The first complex of 4′-(4-methylthiophenyl)-2,2′:6′,2″-terpyridine – A model for terpylated self-assembled monolayers

Robust Self‐Assembled Monolayers of RuII and OsII Polypyridines on Gold Surfaces: Exploring New Potentials

“…Piperazine itself was found to undergo an irreversible oxidation at +0.36 V versus Fc/Fc + . A similar broad shoulder has been noted in the literature for [Ru(Xtpy) 2 ](PF 6 ) 2 , where X=pyrrole,20 and in a recent publication, where X=4‐methylthiophenyl 32…”

“…A similar broad shoulder has been noted in the literature for [RuA C H T U N G T R E N N U N G (Xtpy) 2 ]-A C H T U N G T R E N N U N G (PF 6 ) 2 , where X = pyrrole, [20] and in a recent publication, where X = 4-methylthiophenyl. [32] Complex 6 exhibits a reversible Os II/III redox process at + 0.35 V (vs. Fc/Fc + ) in solution (Figure 2b), which is at a considerably less positive potential than that of the unsubstituted [OsA C H T U N G T R E N N U N G (tpy) 2 ]A C H T U N G T R E N N U N G (PF 6 ) 2 (+ 0.58 V). Unlike the ruthenium equivalent, the CV for 6 is symmetrical and the broad peak due to the irreversible oxidation of the piperazinyl moiety cannot be seen.…”

Stepwise Growth of Ruthenium Terpyridine Complexes on Au Surfaces

“…IRRA, FT-IR, and SER spectroscopies were performed on the respective sample. As model compound, the homoleptic Ru terpyridine complex Ru­(MTP) 2 was synthesized, according to an established protocol . The IRRA spectrum of Ru­(TP, BTP) (red) and the calculated spectrum of Ru­(TP, BTP) (blue) are shown in Figure a together with the FT-IR spectrum of the model compound Ru­(MTP) 2 (black).…”

“…ethanol. The model substances (Figure ) were prepared according to procedures given in the literature. , 1 H NMR, UV/vis, and mass spectroscopies indicated high purity of the prepared substances (Section S1, Supporting Information).…”

Bis(4′-phenyl-2,2′:6′,2″-terpyridine)ruthenium(II): Holding the {Ru(tpy)2}2+ embraces at bay

“…The crystal packing of {M(tpy) 2 } domains is highly conserved and a number of common tpy-embraces have been identified [7,8]. In complexes containing {M(Artpy) 2 } motifs (Artpy = 4 0 -aryl-2,2 0 :6 0 ,2 00 -terpyridine), we have recently described new types of embraces involving face-to-face p-stacking of the pendant aryl ring with tpy pyridine rings [9][10][11][12][13][14]. In this paper, we report the solid state structure of [Ru(Phtpy) 2 ][PF 6 ] 2 Á 4MeCN (Phtpy = 4 0 phenyl-2,2 0 :6 0 ,2 00 -terpyridine) and discuss the general embraces that occur in these extended aryl structures.…”
