Transition metal complexes with photoactive charge‐transfer excited states are pervasive
throughout the literature. In particular,[Ru (bpy) 3] 2+(bpy= 2, 2′‐bipyridine), with its metal …

In molecular photochemistry, charge-transfer emission is well understood and widely
exploited. In contrast, luminescent metal-centered transitions only came into focus in recent …

The photoredox activity of well-known RuII complexes stems from metal-to-ligand charge
transfer (MLCT) excited states, in which a ligand-based electron can initiate chemical …

The molecular ruby [Cr (tpe) 2] 3+ and the tris (bipyridine) chromium (III) complex [Cr
(dmcbpy) 3] 3+ as well as the tris (bipyrazine) ruthenium (II) complex [Ru (bpz) 3] 2+ were …

Photoactive chromium (III) complexes saw a conceptual breakthrough with the discovery of
the prototypical molecular ruby mer-[Cr (ddpd) 2] 3+(ddpd= N, N′-dimethyl-N, N′-dipyridin …

Six-coordinate chromium (III) complexes with high spin-flip (SF) photoluminescence
quantum yields and lifetimes (molecular rubies) have attracted huge interest in the past …

Luminescent complexes of earth-abundant first-row transition metals are of renewed, broad
interest due to their spectroscopic and photochemical properties as well as emerging …

Photodynamic therapy (PDT) used for treating cancer relies on the generation of highly
reactive oxygen species, for example, singlet oxygen 1O2, by light‐induced excitation of a …

Photoactive transition‐metal complexes are luminophores combining high photostability and
long luminescence lifetimes. However, reduced optical performance in aqueous solutions …

The chromium (III) complex [Cr (ddpd) 2][BF4] 3 shows two spin‐flip emission bands in the
near‐infrared spectral region. These bands shift bathochromically by− 14.1 and− 7.7 cm− 1 …
