“…This phenomenon was nicely investigated for the family of classical cyanido-bridged [Ln III (H 2 O) n ] 2 [Pt II (CN) 4 ]·2{Pt II (CN) 4 }·9H 2 O ( n = 6, Ln = La–Lu; n = 5.5, Ln = Eu, Tb) networks (Figure 3, Table 2) [74,75,76,77,78,79]. They are constructed of the coordination layers of a 6-membered metal rings topology based on Pt II and Ln III centres bridged by cyanide ligands within the ab plane (Figure 3a).…”

“…In contrast to the other 4f metal ions, SmPt and EuPt networks reveal the strong lanthanide photoluminescence in the visible range indicating the efficient [Pt II (CN) 4 ] 2− -to-Ln 3+ energy transfer mechanism (Figure 3b) [75,77,78,79]. The polarization-dependent Pt II -based green to orange emission is still observed but significantly decreased through the radiationless energy transfer.…”

“…The sensitization process towards Sm 3+ and Eu 3+ was reported to be sensitive to the hydrostatic pressure. Its increase induces the red shift of the Pt II -centred emission reducing the spectral overlap with Ln 3+ absorption states that leads to the gradual disappearance of the 4f-centred emission [78,79]. The similar effect is caused by the increase of temperature, clearly hampering the lanthanide photoluminescence [79].…”

The similar effect is caused by the increase of temperature, clearly hampering the lanthanide photoluminescence [79]. The strong influence of the Pt–Pt distances on the optical properties was proved by comparison of the closely related [Er III (H 2 O) 6 ] 2 [Pt II (CN) 4 ]·2{Pt II (CN) 4 }·9H 2 O and [Er III (H 2 O) 5 (SO 4 )] 2 [Pt II (CN) 4 ]·{Pt II (CN) 4 }·1.5H 2 O networks [74].…”

Solid-state functional luminescent materials arouse an enormous scientific interest due to their diverse applications in lighting, display devices, photonics, optical communication, low energy scintillation, optical storage, light conversion, or photovoltaics. Among all types of solid luminophors, the emissive coordination polymers, especially those based on luminescent trivalent lanthanide ions, exhibit a particularly large scope of light-emitting functionalities, fruitfully investigated in the aspects of chemical sensing, display devices, and bioimaging. Here, we present the complete overview of one of the promising families of photoluminescent coordination compounds, that are heterometallic d–f cyanido-bridged networks composed of lanthanide(3+) ions connected through cyanide bridges with polycyanidometallates of d-block metal ions. We are showing that the combination of cationic lanthanide complexes of selected inorganic and organic ligands with anionic homoligand [M(CN)x]n− (x = 2, 4, 6 and 8) or heteroligand [M(L)(CN)4]2− (L = bidentate organic ligand, M = transition metal ions) anions is the efficient route towards the emissive coordination networks revealing important optical properties, including 4f-metal-centred visible and near-infrared emission sensitized through metal-to-metal and/or ligand-to-metal energy transfer processes, and multi-coloured photoluminescence switchable by external stimuli such as excitation wavelength, temperature, or pressure.

Complex Compounds / Crystals / High Pressure Luminescence 1 Magnetic FieldsProperties of the polarized emission (energy, intensity, lifetime) of single crystal [Pt(o-phen) (CN),] as functions of temperature (1.9 K s T < 295 K), of homogeneous magnetic fields (0 i H 5 6 T), and of hydrostatic pressures (1 bar I p 5 30 kbar) are reported, and the temperature dependence of the polarized absorption is described. Between T = 1.9 K and room temperature the E l a polarized emission (E: electric field vector; a: crystallographic a axis) and the E l a polarized absorption are blue shifted by -2000 cm-' and 1400 cm-', respectively. Application of a homogeneous magnetic field H l a with field strength H = 6 T shifts the low temperature E l a emission by -190 cm-' to higher energies, shortens the lifetime by two orders of magnitude, and increases the emission intensity by a factor of -18. Increasing hydrostatic pressure between p = 1 bar and 30 kbar reduces the emission energy by -70 cm-'/kbar. The experimental results can be interpreted by a system of coupled complexes of C;, symmetry.

The properties of the lowest excited electronic states under variation of temperature and magnetic field are discussed for single‐crystal [Ru(bpy)3](PF6)2 and for [Os(bpy)3]2+ guests, doped into the [Ru(bpy)3]X2 host material, mainly focusing to the emission properties. Especially, the spectra of the [Os(bpy)3]2+ guests are highly structured and it is possible to identify the three lowest zero‐phonon lines (in the host matrix with the counter ion X = ClO4) and a large number of vibronic components. This structure depends on the counter ion of the host material. Further, a radiationless energy transfer, occurring from the [Ru(bpy)3]2+ hosts to the [Os(bpy)3]2+ guests, is governed by a donor‐donor transfer and a direct donor‐acceptor transfer process. An investigation of the emission decay properties for various acceptor concentrations allows to conclude on a relatively ineffective donor‐donor transport mechanism.
