ABSTRACT
The preparation and properties are described of two types of novel PEG-organized nanoparticles including silica-modified uniform disk-shaped nanoparticles doped with a fluorescent ytterbium cyanoporphyrazine complex; a large enhancement of red emission for both types of nanoparticles is observed in physiological liquids owing to their binding to biomolecules.

A new route to the octacyanoporphyrazine framework based on the interaction of metal sandwich pi-complexes with TCNE has been developed.
ABSTRACT
Lewis acid and Lewis base centers are simultaneously present in the boron-bridged thiophene-containing porphyrinogen 1 that has been synthesized in high yield. Its crystal structure reveals a nonplanar macrocycle; this and the colorless aspect suggest the absence of a delocalized π-electron system. R = NiPr2 .
