“…Another example can be found in the use of ligands with anthracene, a linear polycyclic aromatic hydrocarbon known for its interesting photophysics and rigid geometric structure. Nguyen et al [ 98 ] have synthesized emissive Pd(II) thiosemicarbazones bearing anthracene. The palladium complexes 95 – 97 , shown in Figure 27 , are moderately emissive with quantum yields ranging from 0.10 to 0.25.…”

The synthesis, photophysical properties, and applications of highly fluorescent and phosphorescent palladium complexes are reviewed, covering the period 2018–2022. Despite the fact that the Pd atom appears closely related with an efficient quenching of the fluorescence of different molecules, different synthetic strategies have been recently optimized to achieve the preservation and even the amplification of the luminescent properties of several fluorophores after Pd incorporation. Beyond classical methodologies such as orthopalladation or the use of highly emissive ligands as porphyrins and related systems (for instance, biladiene), new concepts such as AIE (Aggregation Induced Emission) in metallacages or in coordination-driven supramolecular compounds (CDS) by restriction of intramolecular motions (RIM), or complexes showing TADF (Thermally Activated Delayed Fluorescence), are here described and analysed. Without pretending to be comprehensive, selected examples of applications in areas such as the fabrication of lighting devices, biological markers, photodynamic therapy, or oxygen sensing are also here reported.

“…UV-Vis and Photoluminescene Characterizations of NiL UV-Vis absorption and emission spectra of HL and NiL in CH2Cl2 are presented in Figure 4 and Figure 5, respectively. The structureless absorption band at ~405 nm assigned to ππ* transition in NiL is in marked contrast to vibronic absorption band in HL [12]. Also, the complex reveals a severely broad emission band with maximum at 415 nm upon excitation at 330 nm.…”

The X-ray structure of 9-anthraldehyde-4-methyl-3-thiosemicarbazone was firstly determined. The Ni(II) complex with this ligand was prepared upon reaction with chloride salt. Mass spectrometry result confirms correct formulation of the complex. Unusual 1H NMR signal pattern of anthracene moiety reveal cis arrangement cemented by intramolecular p–p stackings between aromatic rings. As a result of this interaction, the electronic structure of anthracene ring is perturbed and gives rise to structureless and broad absorption and emission bands.
