  Spectroscopic and electrochemical properties of cyclopalladated complexes derived from 2,3-diphenylpyrazine

  摘要：

  A comparative study of complexes [Pd(dphpz)(N subset of N)]PF6 [dphpz(-) is the deprotonated form of 2,3-diphenylpyrazine; (N subset of N) is ethylenediamine (En), 2,2'-bipyridine (bpy), o-phenanthroline (phen), dipyrido[a,c]phenazine (dppz), 6,7-dicyanopyrido[f,h]quinoxaline (dicnq)] was made, using H-1 NMR, electronic absorption, and emission spectroscopy, and also cyclic voltammetry. Steric interaction of the dphpz stop phenyl rings leads to significant proton shielding in the carbanionic moiety of the cyclometallated ligand. Introduction of heterocyclic diimines instead of ethylenediamine decreases the desheilding of the dphpz stop protons adjacent to the coordination center. Irrespective of the nature of the N subset of N ligands, the cyclopalladated complexes are characterized by specific parameters of photo-and electrostimulated electron transfer processes involving the Pd(dphpz) orbitals, namely, by the long-wave absorption band with lambda(max) 395 +/- 6 nm and epsilon (2.2 +/- 1.2) x 10(3) 1 mol(-1) cm(-1) stop, the vibrationally structured low-temperature (77 K) luminescence resulting from the spinforbidden optical transfer from the excited to the ground state of the complex (energy E-00 19.27 +/- 0.07 kK, lifetime tau 160 +/- 30 mu s), and the one-electron electroreduction wave with E-1-(2.0 +/- 0.1)V. For the [Pd(dphpz)center dot(N subset of N)](+) complexes containing diazine derivatives of phenanthroline (dppz, dicnq), the degradation of the photoexcitation energy from two electronically excited states can occur as isolated process with successive transfer of electrons to the pi orbitals localized on the remote moieties: [Pd(dphpz)] and diazine fragments of the N subset of N ligands.
