Dual-Metalloporphyrin-Sensitized Photocatalyst for Efficient Solar Hydrogen Production: Importance of Loading Order of Metalloporphyrins

Photoinduced charge separation is crucial for converting solar energy to electrical and chemical energy. In this work, to improve the photoinduced charge separation efficiency at the photosensitizing dye–semiconductor interface, we synthesized two dual ...

Electropolymerized metalloporphyrins

, 2009
The electrocatalytic activities of electropolymerized metalloporphyrins and their applications in the development of nitric oxide (NO)-microsensors and as oxygen reduction catalysts were investigated. By means of a locally developed electrochemical robotic system, the optimization of the functional parameters which determine the sensor properties of Ni-

A Metalloporphyrin-Based Colimetric Nose: "smell-Seeing

261 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2001.To reduce response times, the "Smell-Seeing" array was miniaturized. Deposition of plasticized metalloporphyrin/polymer films on Teflon posts gave microarrays with faster response ...

Metalloporphyrin phototoxicity

Journal of Photochemistry and Photobiology B: Biology, 1990
The phototoxicities of six metalloporphyrin dimethylesters (i.e. cobalt (Co), copper (Cu), manganese (Mn), nickel (Ni), tin (Sn) and zinc (Zn) were investigated. Hemolysis of human erythrocytes and inactivation of two enzymes (acetylcholinesterase and beta-galactosidase) were used to assess the phototoxic efficacy of these metal chelates.

Halogenation of metalloporphyrins

Russian Journal of Bioorganic Chemistry, 2000
We found that thionyl chloride can chlorinate porphyrin complexes with transient metals (Pd, Ni, or Cu) at the free β andmeso-positions of the porphyrin macrocycle. A more prolonged or rigorous treatment also causes the chlorination of side alkyl substituents, mainly, methyl groups.
