“…For example, in order to construct complexes with remarkable photoluminescent properties, aromatic organic ligands and d 10 metal ions deserve the researchers' intensive investigation. Aromatic organic ligands may display photoluminescence in the solid state [14][15][16][17][18], while the incorporation of d 10 metal ions is found to be useful to enhance the luminescence intensity and lifetime of their hybrid complexes [19][20][21].…”

“…Hexaazatriphenylene (HAT, Figure 1) is the simplest member of a family of electron‐deficient tris(bidentate) ligands with considerable non‐innocent character 9, 10, 11, 12, 13, 14. An area in which the potential non‐innocence of HAT ligands has not yet been exploited is molecular magnetism, principally because stable, synthetically useful radical derivatives of HAT are unknown.…”

Strong Exchange Coupling in a Trimetallic Radical‐Bridged Cobalt(II)‐Hexaazatrinaphthylene Complex

Reducing hexaazatrinaphthylene (HAN) with potassium in the presence of 18‐c‐6 produces [{K(18‐c‐6)}HAN], which contains the S=1/2 radical [HAN].−. The [HAN].− radical can be transferred to the cobalt(II) amide [Co{N(SiMe3)2}2], forming [K(18‐c‐6)][(HAN){Co(N′′)2}3]; magnetic measurements on this compound reveal an S=4 spin system with strong cobalt–ligand antiferromagnetic exchange and J≈−290 cm−1 (−2 J formalism). In contrast, the CoII centres in the unreduced analogue [(HAN){Co(N′′)2}3] are weakly coupled (J≈−4.4 cm−1). The finding that [HAN].− can be synthesized as a stable salt and transferred to cobalt introduces potential new routes to magnetic materials based on strongly coupled, triangular HAN building blocks.

“…Beside the homoligand polycyanidometallates, [M(CN) x ] n− (x = 2, 4, 6, and 8), the photo-luminescent d–f coordination networks were prepared using the heteroligand tetracyanidometallate complexes, [M II (L)(CN) 4 ] 2− (M = Ru, Os), where two positions of the octahedron are blocked by the aromatic N,N-bidentate organic ligands, L [111,112,113,114,115,116,117,118,119]. Depending on the selected L ligand, exemplified by 2,2’-bipyridine (2,2’-bpy), 1,10-phenanthroline (phen), or 2,2’-bipyrimidine (bpym), these heteroligand cyanide complexes of Ru II and Os II reveal the intrinsic green to red emission of the metal-to-ligand charge transfer (MLCT) origin [33].…”

Lanthanide Photoluminescence in Heterometallic Polycyanidometallate-Based Coordination Networks

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.
