“…Through the use of other chelates such as N , S ligands, ferrocene has been incorporated – by the Lopez group, for instance – onto palladacycles . Key ligands that are most useful for stabilizing gold and palladium NPs are ferrocene‐ and biferrocene‐containing thiolates, and these ligands also serve as self‐assembled monolayers . The Bilstein group has designed N‐heterocyclic carbenes (NHCs) containing a ferrocenyl substituent (or substituents) on the nitrogen atom(s) and has synthesized N , N′ ‐diferrocenyl heterocycles …”

The appearance of ferrocene in the middle of the 20th century has revolutionized organometallic chemistry and is now providing applications in areas as varied and sometimes initially unexpected as optical and redox devices, battery and other materials, sensing, catalysis, including asymmetric and enantioselective catalysis, and medicine. The author presents here a general, although personal, view of ferrocene's chemistry, properties, functions, and applications through a literature survey involving both historical and up‐to‐date trends and including examples of his group's research in a number of these areas. The review gathers together general features of ferrocene chemistry and representative examples of the salient aspects. Its focus is on ferrocene's basic properties, ferrocene‐containing ligands, the ferrocene/ferricinium redox couple, ferrocene mixed‐valence and average‐valence systems, the ferricinium/ferrocene redox shuttle in catalysis, ligand‐exchange reactions, ferrocene‐containing polymers, ferrocene‐containing structures for cathodic battery and other materials, ferrocenes in supramolecular ensembles, liquid crystals, and nonlinear optical materials, ferrocene‐containing stars and their electrostatic effects, ferrocene‐containing dendrons, dendrimers, and nanoparticles (NPs) and their application in redox sensing and catalysis, and ferrocenes in nanomedicine.

“…The thermolysis of Pd hexadecanethiolate spin‐coated on a Si surface (Figure 1) was studied at different temperatures ranging from 30 to 250 °C using optical reflectance and FTIR spectroscopy (Figure 2). The pristine film shows a broad peak in the reflectance spectrum (Figure 2a) on a falling background 34. When the films are subjected to increasing temperatures, the peak gets weaker and the reflectance becomes increasingly uniform over the entire range of wavelengths, typical of metal films 25.…”

Nanocrystalline metallic Pd films have been produced by thermolysis of Pd hexadecanethiolate deposited on a Si surface. The particle size was in the range of 50-60 nm based on electron and atomic force microscopy. The Pd surface produced was found to be surface-enhanced Raman scattering (SERS) active with an enhancement factor of approximately 10(5). The electron-resist behavior of Pd thiolate is exploited in conceptualizing a prototype chip with patterned Pd regions that are SERS active, called "SERS bits", which host different biomolecules.

“…The functionalized particles are observed to show reversible voltammetric behaviour. Redox-active biferrocene-functionalized gold and palladium MPCs have been prepared and electrodeposited on ITO, GCE and metal electrode surfaces [62][63][64]. The clusters undergo two-step oxidation reactions in aprotic solvents and the second oxidation reaction is reported to result in the electrodeposition of the Au clusters.…”

“…The shift in the absorbance maximum as a function of applied potential is reported to be predominantly due to the charging of the metal core. The contribution by the redox-active moiety, though small, should also be considered [62][63][64].…”
