Since the 1980s, pressure-sensitive paint (PSP) has been used as an optical pressure sensor for measuring surface pressure on aircraft models in wind tunnels. Typically, PSPs have utilized platinum(II)-5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)-porphyrin due to its high pressure sensitivity, phosphorescence lifetime of ∼50 μs, reasonable quantum yield of emission, and resistance to photo-oxidation. This work investigates the photophysics and electronic structure of metal complexes of 5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)-porphyrin, namely, Zn(II), Pd(II), and Ir(III), as potentially improved luminophores for polymer-based PSPs.

The title compound, [Zn(CHClNO)Cl], is a dinuclear zinc(II) complex with three chlorido ligands and one penta-dentate ligand containing quinolin-8-olato and bis-(pyridin-2-ylmeth-yl)amine groups. One of the two Zn atom adopts a tetra-hedral geometry and coordinates two chlorido ligands with chelate coord-ination of the N and O atoms of the quinolin-8-olato group in the ligand. The other Zn atom adopts a distorted trigonal-bipyramidal geometry, and coordinates one chlorido-O atom of the quinolin-8-olato group and three N atoms of the bis-(pyridin-2-ylmeth-yl)amine unit.

Herein, we describe a Zn-catalyzed atom-economical, inexpensive, and sustainable method for preparing a broad spectrum of substituted olefins utilizing alcohols as the main precursor. Using a Zn(II) complex [ZnLCl] () of the redox-noninnocent ligand 2-((4-chlorophenyl)diazenyl)-1,10-phenanthroline (), various ()-olefins were prepared in good yields by coupling alcohols with sulfones and aryl cyanides under an inert atmosphere. Under an aerial atmosphere, vinyl nitriles were isolated in up to 82% yield reacting alcohols with benzyl cyanides in the presence of .

Five metal dithiocarbamate complexes [M(PTHIQDTC)] [where PTHIQDTC is (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline dithiocarbamate anion and M is Ni(II) (1), Sn(II) (2), Hg(II) (3), Pb(II) (4) and Zn(II) (5)] were synthesized from the reaction of MX (X is Cl for 1-3 and OAc for 4-5) with ligand of triethylammonium (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline dithiocarbamate [EtNH][PTHIQDTC] in methanolic solution at room temperature. The five complexes were characterized by IR, H andC NMR, mass spectrometry, elemental analysis and TGA analysis. Recrystallization of [Zn(PTHIQDTC)] (5) in dimethylsulfoxide (DMSO) converts 5 to [Zn(PTHIQDTC)(DMSO)] (6).
