THz-EPR spectroscopy provides direct access to the low-lying electronic structure and spin–phonon coupling in iron(II) spin crossover (SCO) complexes. Quantification of the high-spin fraction (γHS) a...

Light-activatable iridium(III) anticancer prodrugs demonstrate how chalcogen coordination controls photoinduced therapeutic activity. Upon visible-light irradiation, sulfur- and selenium-based caging....

Tungsten oxide (WO3) thin films find applications in a variety of fields, including chromism, gas sensing, and photoelectrochemistry. In the context of each application, the necessity arises for the identification of specific material properties. In this study, we propose a sol–gel methodology that facilitates the modulation of material properties through the precise manipulation of synthesis parameters. The calcination temperature, template concentration, and number of dip coating steps were found to have a significant impact on the crystallinity, (002) facet exposure, surface area, band gap, and absorption efficiency of the mesoporous WO3 thin films. In the context of photoelectrochemical water oxidation, it has been determined that the crystallinity, band gap, and light absorption of the material are positively correlated with enhanced bulk processes. Photocurrent values of up to 3.75 mA cm–2 at 1.23 V vs RHE under AM 1.5 G illumination were achieved, while external quantum yields of 58% were also obtained. The systematic correlation between synthesis parameters and material properties, as outlined in this study, offers a straightforward and efficient method for adjusting WO3 thin film properties to meet specific application requirements.

Spin-crossover compounds are molecular switches with functional high- and low-spin states. Here, the authors present an iron(III) complex that additionally also allows for continuous population of bot...

Heteroleptic coordination cages enable not only a high control over the cavity properties but also multifunctionality. However, their synthesis is far from trivial and often relies on precious 4d and ...

The total spin of a metal center can be switched in different ways. In this concept, the phenomenon spin crossover is compared with coordination-induced spin-state switching. The impact of the switch....
