2,3,5-triphenyltetrazolium chloride (TTC) may convert into phenyl-benzo[c]tetrazolocinnolium chloride (PTC) and 1,3,5-triphenylformazan (TPF) under irradiation with light. The latter reaction, albeit enzymatically rather than photochemically, is used

Increasing the metal-to-ligand charge transfer (MLCT) excited state lifetime of polypyridine iron(II) complexes can be achieved by lowering the ligand's π* orbital energy and by increasing the ligand field splitting. In the homo- and heteroleptic co

The relative yield of photoproducts of N-(α-phenylethyl)salicylimine can be modulated by variation of the excitation wavelength, as we investigate by matrix-isolation IR spectroscopy with sequential irradiation and by ultrafast transient absorption.

Ionic Liquids [M 3+ ][A − ] 3 with Three‐Valent Cations and Their Possible Use to Easily Separate Rare Earth Metals

We introduce a simple way to liquify rare earth metals (REM) by incorporating the corresponding cations, in particular Eu3+, La3+, and Y3+, into polyvalent ionic liquids (ILs). In contrast to conventional methods, this is achieved not by transforming
