Attachment of Luminescent Neutral “Pt(pq)(C≡CtBu)” Units to Di and Tri N-Donor Connecting Ligands: Solution Behavior and Photophysical Properties

Abstract

The effects of concentration, temperature and solvent properties on the equilibrium have been studied. The optical properties of these systems have been investigated by UV-visible absorption and emission spectroscopies in solid state and in solution, and the nature of the transitions and the excited state analyzed by theoretical calculations on 2a.

Stayin’ Alive—Organoplatinum Complexes

“…In a more classical way, using non-organometallic cis-[PtCl2 Another type of interesting luminescent material is reported in the paper by Elena Lalinde, Maria Teresa Moreno and coworkers [19]. The here reported, binuclear [{Pt(pq)(C≡C t Bu)}2(μ-L)] and trinuclear [{Pt(pq)(C≡C t Bu)}3(μ-L)] (L = μ-1,3,5-tris(pyridine-4-ylethynyl)benzene; Hpq = phenylquinoline) complexes were formed by bridge-splitting reactions with [Pt(pq)(μ-κCα:η 2 -C≡C t Bu)]2.…”
