Preparation and Characterization of Some Cyclometalated Pt(II) Complexes from 2-Phenylpyridine and 2-(2'-Thienyl)pyridine.

Cyclometalated platinum(ii) diimine complexes: synthetically tuning the photophysical and electrochemical properties

“…It is surprising, then, that only two studies of archetypical cyclometalated diimine complexes of the type [Pt( ppy)(bpy)] + are recorded in the literature. 37,38 Therefore, we have undertaken the development of a library of 16 heteroleptic [Pt( ppy)(bpy)] + complexes and characterized their structural, photophysical, and excited state properties.…”

“…Emission spectra and excited-state lifetimes were measured in DMF solution at room temperature after bubbling with argon for 10 min; lifetimes were measured with a N 2 laser (3.5 ns pulse). Quantum yields were calculated using [Ru(bpy) 3 ](PF 6 ) 2 as the reference standard 37.…”

Thermo‐ and Mechano‐Triggered Luminescence ON/OFF Switching by Supercooled Liquid/Crystal Transition of Platinum(II) Complex Thin Films

“…[ 7h,10,11,16 ] This thermal process was also confirmed by variable‐temperature microscopic observations (Figure S3). In contrast, the melting points of 1‐Cl [ 17 ] and 1‐Br ( T m = 458 K and 443 K, respectively; Figure 1e) are significantly higher than those of 2‐X, indicating the importance of the low‐symmetry of P 6,6,6,14 ions for lowering the melting point. Thus, we have succeeded in obtaining metastable supercooled ionic liquid phases for 2‐Cl and 2‐Br and thermal crystallization of their supercooled liquid phases using P 6,6,6,14 cations.…”

“…It was found [1][2][3][4][5][6][7] that the luminescent characteristics of these complexes depend on a great number of factors, including the nature of the central ion, the donor-acceptor properties of ligands, the solvent polarity, and the presence of molecular oxygen and halocarbon vapors. This work is aimed at studying the effect of water vapors on the luminescence of the cation of 2-phenylpyridinate ethylenediamine of platinum(II) ( [PtEnPpy] + ), immobilized on the surface of an MF-4SK perfluorinated cation-exchange membrane (CEM) (OAO Plastpolymer, St. Petersburg, Russia) (Fig.…”

“…The [PtEnPpy]Cl complex was synthesized using the known technique [2]. Before the complex immobilization, a CEM 10 × 20 × 0.2 mm in size was boiled for one hour in concentrated nitric acid and then washed with distilled water to neutral reaction.…”
