Synthesis and physical properties of tunable aryl alkyl ionic liquids based on 1-aryl-4,5-dimethylimidazolium cations
Beilstein J. Org. Chem. 2024, 20, 1278–1285, doi:10.3762/bjoc.20.110
- well known that the hydrogen atom at the C2 carbon atom of the imidazole core is more acidic as those in the C4/C5-position, where the methyl groups are expected to also have a significant effect on the molecular interactions. Platinum complexes using the 4,5-dimethylimidazole motif as a ligand were
Repurposing the anticancer drug cisplatin with the aim of developing novel Pseudomonas aeruginosa infection control agents

- glucose and 0.4 g/L casamino acids). For marker selection in P. aeruginosa, 30 μg mL−1 gentamycin (Gm), 50 μg mL−1 tetracycline (Tc), 100 μg mL−1 streptomycin (Strep) or 200 μg mL−1 carbenicillin (Cb) were used, as appropriate. Platinum complexes and solution preparation for MIC assay Cisplatin
- , transplatin, cDPCP, oxaliplatin, K2PtCl4 and cis-PtCl2(CH3CN)2 were purchased from Sigma-Aldrich were used as received. Platinum complexes cis-PtCl2(Py)2 [13][14] and cis-PtCl2(PPh3)2 [15] were prepared according to the reported procedure. For minimal inhibitory concentration (MIC) assays, cisplatin, cDPCP
Recent advances in phosphorescent platinum complexes for organic light-emitting diodes
Beilstein J. Org. Chem. 2018, 14, 1459–1481, doi:10.3762/bjoc.14.124
- square planar platinum(II) complexes bearing π-conjugated chromophoric ligands playing a key role in such respect. In this contribution, the most recent and promising trends in the field of phosphorescent platinum complexes will be reviewed and discussed. In particular, the importance of proper molecular
- ; electroluminescence; OLED; phosphorescence; platinum complexes; Introduction Photoactive TMCs have attracted enormous attention in the last two decades because of their peculiar photophysical and rich redox properties, which make them appealing from both fundamental research and technological applications points of
- of phosphorescent platinum complexes for PhOLEDs with a special emphasis on the most recent advances. It should be noted that this contribution is not indented to be comprehensive and readers are invited to refer elsewhere for previous examples of platinum emitters [15][16][17][18]. In particular, we
Enhanced quantum yields by sterically demanding aryl-substituted β-diketonate ancillary ligands
Beilstein J. Org. Chem. 2018, 14, 664–671, doi:10.3762/bjoc.14.54
- groups as substituents in acetylacetonate (acac) auxiliary ligands can have a positive influence on the emission properties of platinum(II) phosphors [35][36][37][38]. The use of mesityl and duryl groups enhanced the quantum yield of platinum complexes with a variety of C^C* cyclometalating ligands [18
- ][39][40][41]. We herein present the synthesis and photophysical properties of two new C^C* cyclometalated platinum complexes. Both are based on the original 3-methyl-1-phenylimidazolium (MPIM) ligand system which together with the acac auxiliary ligand showed only a very low quantum yield of 7%. We
- the platinum complexes were performed under an argon atmosphere and by exclusion of light, using flame-dried Schlenk tubes. Solvents of at least 99.0% purity were used. DMF was dried according to standard methods and stored over molecular sieve (3 Å) under argon atmosphere. Dichloro(1,5-cyclooctadiene
Methylpalladium complexes with pyrimidine-functionalized N-heterocyclic carbene ligands
Beilstein J. Org. Chem. 2016, 12, 1557–1565, doi:10.3762/bjoc.12.150
- “Catalytica” bispyrimidine system, for the biscarbene system the palladium complexes turned out to be more stable than the corresponding platinum complexes under the reaction conditions [31][32], although Peter Hofmann had recently shown the stability and reactivity of the platinum-alkyl complexes with bis
Bi- and trinuclear copper(I) complexes of 1,2,3-triazole-tethered NHC ligands: synthesis, structure, and catalytic properties

- and platinum complexes containing 1,2,3-triazole-tethered NHC ligands. The obtained palladium complexes displayed high activity in aqueous Suzuki–Miyaura cross-coupling reactions. We are interested in the synthesis and use of functionalized NHC ligands [20][28][29][30][31]. Herein, the synthesis
Self-assembly of metallosupramolecular rhombi from chiral concave 9,9’-spirobifluorene-derived bis(pyridine) ligands
Beilstein J. Org. Chem. 2014, 10, 432–441, doi:10.3762/bjoc.10.40
- heterochiral one in both cases – the palladium and the platinum complexes and independent of the solvents we used. This corresponds to an amplification of the homochiral stereoisomers via self-recognition by a factor of approximately three. Although these NMR spectra already provide a very good proof for the
Supramolecular hydrogels formed from poly(viologen) cross-linked with cyclodextrin dimers and their physical properties
Beilstein J. Org. Chem. 2012, 8, 1594–1600, doi:10.3762/bjoc.8.182
- adding selenium or platinum complexes yields supramolecular assemblies of bis(molecular tube)s cross-linked with the β-CD dimer, which form nanofibers [12][13][14][15]. Moreover, mechanically linked polyrotaxane with the α-CD and poly(ethylene glycol) (PEG) produces a hydrogel material, which exhibits
