Diethynyldiazafluoren-9-ylidene as a πcross-Conjugated Platform for Redox Active Transition Metal Fragments
Nauroozi, Djawed,Bruhn, Clemens,Faust, Rüdiger
, p. 2553 - 2557 (2019)
Synthetic routes were developed to attach three redox-active metal fragments to cross-conjugated 3-methylidenepentadiyne covalently expanded by diazafluorenylidene: The two alkyne termini of this new ligand were end-capped via a phenylene spacer with ethy

The forces required for the detachment of ferrocene (Fc) from β-cyclodextrin (βCD) in a single host (βCD)-guest (Fc) complex were investigated using force spectroscopy under electrochemical conditions. The redox state of the guest Fc moiety as well as the structure of the supporting matrix was found to decisively affect the nanomechanical properties of the complex. This journal is

A series of ferrocenyl phenylethynyl rods 1-11 were designed, and synthesized by a Pd catalysed Sonogashira cross-coupling, and oxidative homo-coupling reactions. The ferrocenyl moieties in the rods 1-11 are attached at the para/meta position of phenylethynyl unit or at the acetylenic unit. The effect of enhancing the conjugation, and connectivity (meta/para) on the photonic and electrochemical properties were explored. The para linkage, and butadiynyl linkage lower the band gap in the rods. The meta linked ferrocenyl phenylethynyl rods 2, 4, and 10 show good HOMO-LUMO separation compared to para linked rods 1, 3, 9. The single crystal X-ray structures of rods 2, 4, 10, 14 and 19 are reported. The ferrocene units in rods 2, 4, and 10 are in a trans configuration with respect to the phenyl ring.

This study reports the synthesis of new pyridyl ligands incorporating an alkyne entity with an end-capping ferrocenyl moiety: 1-(ferrocenylethynyl)-4-((4-pyridyl)ethynyl)benzene (FEPEB), 1-ferrocenyl-6-(4-pyridyl)hexatriyne (FPHT), and 1-ferrocenyl-4-(4-pyridyl)-butadiyne (FPBD). The complexes W(CO)4(L)(FEPEB) (L = CO, PPh3, P(OMe)3, PMe3), W(CO)4(L)(FPHT) (L = CO, PPh3, P(OMe)3, PMe3), and W(CO)5(FPBD) are obtained by ligating FEPEB, FPHT, and FPBD to W(CO)4(L)(THF). The energy of tungsten metal to pyridyl π* charge transfer (MLCT) depends on both the pyridyl ligand and the ancillary ligand, L. Treating FPHT and FPBD with MeI causes N-methylpyridinium derivatives to form, which exhibit a strong low-lying charge-transfer band. As a comparative study, the complexes 1-(ferrocenylethynyl)-4-((4-nitrophenyl)ethynyl)-benzene (FENEB) and 1-(ferrocenylethynyl)-4-((4-aminophenyl)ethynyl)benzene (FEAEB) have also been synthesized. X-ray analysis has been employed to examine the structures of 1-(ferrocenylethynyl)-4-ethynylbenzene, W(CO)4(PPh3)(FEPEB), W(CO)5(FPHT), and 1,8-diferrocenyloctatetrayne.
