Summary: Cancer is a significant global health threat and new treatments are needed to improve patient prognosis. Unconventional platinum complexes, consisting of polypyridyl ligands and diaminocyclohexane, have shown anticancer activity in previously undruggable KRAS mutated cells, with cytotoxicity values up to 100 times better than cisplatin. Inspired by these complexes, six novel cyclometallated examples were designed and their fluorescence was used to study the mechanism of action of platinum drugs. The cytotoxicity results showed that these cyclometallated complexes have different activity compared to the inspiring complexes, but are as cytotoxic as cisplatin and have higher selectivity indices in breast cancer cell lines. Complexes 1b, 2a, and 3b exhibited particularly high selectivity indexes. Further investigation revealed their good affinity to ctDNA, especially CMCs 1a and 3b. The fluorescence of these complexes was successfully utilized in calculating their DNA binding affinity.

Summary: A series of cyclometallated platinum(II) complexes incorporating a rare and unique NC-chelating, pyridyl-pyridylidene ligand have been prepared through an unusual protodemethylation reaction. These complexes can incorporate acetylacetonate (acac) or 2-picolinate (pic) or 8-hydroxyquinolate as auxiliary ligands, and display unusual dual emission in a frozen glass.

Summary: A series of five platinum (II) complexes based on 2-phenylpyrimidine ligands were designed in this study. It was found that the presence of substituents on the phenyl ring leads to a red shift of the lowest-energy absorption band and results in emission in the solid state.

Summary: Self-assembly relies on the ability of smaller entities to arrange into organized systems, with the design of the media playing a crucial role. The media determines the self-assembly pathway and can control the wrapping process of supramolecular homo-aggregates by a different crystal lattice component. This reverse coating process is controlled by the media composition and could lead to the construction of hierarchical supramolecular structures.

Summary: Two series of Pt(II)-cyclometallated compounds with different (NCN)-C-boolean AND-N-boolean AND ligands and alkynyl-chromophore ligands were synthesized and characterized. The presence of weak intermolecular contacts leading to dimerization or aggregation was observed in the crystal structures of some compounds. The photophysical characterization showed two emission bands in solution, originating from the N<^>C<^>N ligands and (MLCT)-M-3/(ILCT)-I-3 transitions, and the formation of excimers with near-infrared (NIR) emission was identified in compounds with phenanthrene chromophores. Aggregates emitting at around 650 nm were also detected in acetonitrile/water mixtures.

Summary: A cationic carbazole-bridged biscyclometalated diplatinum complex 4 has been synthesized and characterized, showing different fluorescence properties under different solvent conditions and enhanced phosphorescent emission in aggregate state. Analysis through X-ray and density functional theory calculations revealed that the phosphorescent emission enhancement is mainly caused by the oxygen-shielding effect and molecular rigidification-induced decrease of nonradiative decays in the aggregate state.

Summary: A cyclometallated rhodium complex was used as a catalyst for the quantitative nucleophilic fluorination of a range of acyl chlorides to acyl fluorides. The catalyst showed high yields and could be separated, regenerated, and reused. The reaction mechanism was proposed to involve a nucleophilic Rh-F bond based on graphical kinetic analysis and DFT calculations.
