An unprecedented cyclometallated platinum(II) complex incorporating a phosphinine co-ligand: synthesis and photoluminescence behaviour.
نویسندگان
چکیده
The first luminescent cyclometallated platinum(II) complex bearing phosphinine co-ligands is reported. The long-lived luminescence, which it displays at 77 K, is assigned to a phosphinine-localised triplet excited state on the basis of electrochemical data and TD-DFT calculations.

Novel N^C^N-cyclometallated platinum complexes with acetylide co-ligands as efficient phosphors for OLEDs†
Two new cyclometallated platinum(II) complexes have been prepared that incorporate a terdentate N^C^N-coordinating ligand and a monodentate acetylide co-ligand. The complexes, namely [PtL– C^C–C6H3F2] and [PtL 6–C^C–C6H3F2] (where HL 3 1⁄4 5-methyl-1,3-di(2-pyridyl)benzene; HL 1⁄4 5-mesityl-1,3-di(2-pyridyl)benzene; H–C^C–C6H3F2 1⁄4 3,5-difluorophenylacetylene), were prepared by ligand metathes...

متن کاملSynthesis of Cis-Diammine (1,1-cyclobutane dicarboxylate) Platinum(II)
Platinum-based anticancer drugs are chemotherapeutic agents to treat cancer. Carboplatin (cis diammine cyclobutane dicarboxylate platinum (II)) is a second generation drug that has less toxic than cisplatin, allowing for high dosages. In the first stage, 1,3-Cyclobutane dicarboxylic acid, a key intermediate for the preparation of carboplatin, have been synthesized in good yields using diffe...
