Multiple electrochemically accessible colour states in surface-confined metal–organic monolayers: stepwise embedding of individual metal centres
نویسندگان
چکیده
Sequential embedding of metal complexes 4?-(pyridin-4-yl)-2,2?:6?,2??-terpyridine to a surface-enhanced supports pre-functionalized with templating layer results in hetero-bimetallic (Os–Fe, Co–Fe) and hetero-trimetallic (Co–Os–Fe) monolayer materials.

Non-conventional coordination of cavity-confined metal centres.
WIDEPHOS, a β-cyclodextrin cavitand bearing two introverted P(III) donor atoms, readily accommodates two converging Au-X fragments (X = Cl, Br, I). In the corresponding [(WIDEPHOS)(AuX)(2)] complexes, severe steric crowding within the cavity results in one of the P-Au-X rods deviating from linearity, as revealed by an X-ray diffraction study and unusual (31)P magnetic shielding of one of the tw...
متن کاملSemiconducting polymer thin films by surface-confined stepwise click polymerization.
Surface-confined stepwise click polymerization was used to prepare surface-attached thin films of semiconducting polymers. These highly uniform films showed extended UV/vis absorption characteristics and a remarkable degree of molecular organization with a unidirectional alignment of the polymer chains normal to the surface.

The Shockley surface state on Cu(111) reacts sensitively to the perturbation by molecular adsorbates on the surface. In the porous structure of a metal-coordinated molecular network on Cu(111), the surface state is confined to a series of discrete states. Energy and momentum of eigenstates in the pores are related to both the energy dispersion of the free surface state and the geometric and ene...
متن کاملSurface States, Surface Metal-Insulator, and Surface Insulator-Metal Transitions ∗
I present an informal discussion of various cases where two-dimensional surface metal-insulator structural and charge-density-wave instabilities driven by partly filled surface states have been advocated. These include reconstructions of clean semiconductor surfaces and of W(100) and Mo(100), as well as anomalies on the hydrogen-covered surfaces H/W(110) and H/Mo(110), and possibly alkali-cover...
متن کاملElectrochemically induced morphology and volume changes in surface-grafted poly(ferrocenyldimethylsilane) monolayers.
Poly(ferrocenyldimethylsilanes), composed of alternating ferrocene and dimethylsilane units in their main chain and featuring a thiol end group, were self-assembled to redox-active monolayers on gold. Electrochemical atomic force microscopy was employed to study the morphology of the monolayers as a function of the applied potential in situ. Surface plasmon resonance spectroscopy and spectrosco...
