Herein, we highlight relevant π-systems based on six-membered phosphorus heterocycles as well their potential in bio- and optoelectronic applications.
Oligo(p-phenylenevinylene) (oPPV) wires of various lengths featuring pyridyls at one terminal and C60 moieties the other, have been used as molecular building blocks in combination with porphyrins to construct a novel class electron donor-acceptor architectures. These architectures, which are based on non-covalent, directional interactions between zinc centers pyridyls, characterized by nuclear magnetic resonance spectroscopy mass spectrometry. Complementary physico-chemical assays focused...
Zinc porphyrin-functionalized fullerene [C60] derivatives have been synthesized and used to prepare titania-based composites. The electrochemical properties HOMO LUMO levels of the photosensitizers were determined by measurements. Raman IR techniques study chemical groups present on titania surface. Absorption composites measured in solid state diffuse reflectance UV-Vis spectra (DRS). zeta potential aggregate sizes using dynamic light scattering (DLS) electrophoretic (ELS) techniques....
Visible-light-activated photocatalysts based on samarium-doped, europium-doped, and gadolinium-doped nickel aluminates (SmNA, EuNA, GdNA) were synthesized.

Ultraviolet-visible-near-infrared (UV-Vis-NIR) spectra revealed that REMs-doped catalysts absorb in full...
Thermal annealing of nanodiamonds with diameters a few nanometers (in an inert atmosphere and at temperatures in the range: 1500-1800 °C) leads to formation carbon nano-onions (CNOs) between 5 6 nm, which correspond nanostructures six eight graphitic layers.

The chemistry of linearly fused systems based on six‐membered phosphorus heterocycles is currently experiencing an astonishing evolution. Even though the analogs naphthalene and anthracene were first synthesized in late 1960s, laterally have recently demonstrated outstanding performances as biomarkers, sensors, luminescent for organic electronics. In this microreview, we provide a comprehensive revision relevant from their origin to latest advances largest derivatives.
