A protocol for the bottom-up self-assembly of nanogaps is developed through molecular linking of gold nanoparticles (AuNPs). Two π-conjugated oligo(phenylene ethynylene) molecules (OPE) with dithiocarbamate anchoring groups are used as ligands for the AuNPs. OPE-4S with a dithiocarbamate in each end of the molecule and a reference molecule OPE-2S with only a single dithiocarbamate end group. Th...

A fluorescent poly(phenylene ethynylene) containing calix[4]arene-based receptor units has a sensitivity to quenching by the N-methylquinolinium ion that is over three times larger than that seen in a control polymer lacking calix[4]arenes.

Pd-catalyzed Sonogashira cross-coupling reactions were used to synthesize novel π-conjugated oligothienylene-ethynylene dendrons and their corresponding terpyridine-based ligands. Their complexation with Ru(II) led to interesting novel metallodendrimers with rich spectroscopic properties. All new compounds were fully characterized by (1)H and (13)C NMR, as well as MALDI-TOF mass spectra. Densit...

Novel derivatives of heterocyclic azo compounds have been synthesized through a free catalyst reaction. The structures the were confirmed by using different techniques such as 1H-NMR, 13C-NMR, and mass spectroscopy. prepared evaluated corrosion inhibitors for mild steel after inhibitory performance toward in 0.1 M HCl solution. derivatives, i.e. (1,1'-(((1E,1'E)-1,4-Phenylenebis(diazene-2,1-diy...

White-light broadband emission in the visible range from low-dimensional halide perovskites is commonly attributed to structural distortions lead bromide octahedra. In this paper, we report Dion–Jacobson-phase two-dimensional (2D) based on short aromatic diammonium cations, p-phenylene (pPDA), m-phenylene (mPDA), and two 1D compounds templated by o-phenylene (oPDA). All of exhibit white-light e...

Graphene prepared with p-phenylene diamine as reducing reagent was stably dispersed in ethanol, and its film, prepared by electrophoretic deposition on ITO, exhibited high conductivity.

Both pentafluorophenylmercury chloride and trimeric perfluoro-ortho-phenylene mercury interact with phenanthrene to form phosphorescent adducts which exhibit extended binary stacks in the solid state.

Formation and characterization of nanocrystallite spheres from a hybrid of functionalized cross-conjugated poly(p-phenylene) and C(60) are reported.

Decreased spectral overlap between a donor biotinylated poly(p-phenylene ethynylene) and a chromophore-labeled streptavidin acceptor leads to better observed fluorescence resonance energy transfer.

A peptide aptamer, which was originally identified by affinity screening for hyperbranched poly(phenylene vinylene) (hypPPV), functioned as an excellent dispersant for hypPPV nanoparticle formation.
