Synthesis, Luminescence, Electrochemistry, and Ion-Binding Studies of Platinum(II) Terpyridyl Acetylide Complexes

Vivian Wing-Wah Yam, +3 more
- 22 Sep 2001 - 
TL;DR: A series of platinum terpyridyl acetylide complexes, [Pt(trpy)(C⋮CR)]PF6 (R = C6H5,C6H4Cl-4, C 6H4OCH3-4 and C 6 H4NO2-4), have been synthesized and characterized in this paper.
Journal ArticleDOI

Organic light-emitting materials based on bis(arylacetylide)platinum(II) complexes bearing substituted bipyridine and phenanthroline ligands: photo- and electroluminescence from 3MLCT excited states.

Siu-Chung Chan, +5 more
- 01 Oct 2001 - 
TL;DR: The synthesis and photophysical and electroluminescent properties for a series of platinum(II) alpha-diimine bis(arylacetylide) complexes and the impact of different solvents, substituents on the diimine ligands, and complex concentrations upon their emissive behavior have been examined and demonstrates that their emission energies can be systematically modified.
Journal ArticleDOI

- 02 Mar 2000 - 
TL;DR: In this article, a spectroscopic and structural investigation of binuclear silver(I) complexes supported by aliphatic phosphine ligands, namely [Ag(PCy3)(O2CCF3)]2 (1), [Ag2(μ-dcpm)2]X2 (X = CF3SO3, 2; PF6, 3; dcpm = bis(dicyclohexylphosphino)methane), and [Ag 2(mdcpm)(μ-O2ccF3] (4), is described.
Journal ArticleDOI
