A molecular database for developing organic solar cells

A molecular database for developing organic solar cell

Harvard researchers have released a massive database of more than 2 million molecules that might be useful in the construction of solar cells that rely on organic compounds for construction of organic solar cells for the production of renewable energy. Developed as part of the Materials Genome Initiative launched by the White House’s Office of … more…

Lab Reproduction of Marine Compound with Antibiotic Properties

Barcelona, Spain (Scicasts) – Bacterial resistance to drugs leads pharmaceutical labs to be in constant search for new antibiotics to treat the same diseases. For the last thirty years, the sea bottom has yielded a wealth of substances with properties of interest to the pharmaceutical industry.
 
Isolated from a marine microorganism off the coast of Alicante by the company BioMar, baringolin shows promising antibiotic activity at a very low concentration. The Combinatorial Lab headed by Fernando Albericio at the Institute for Research in Biomedicine (IRB Barcelona), which collaborates with BioMar, has now synthesized this molecule and revealed its structure. Today's results open up the possibility to better understand how this substance works and to design derivatives to turn into a viable drug in the next 10 years. These findings are published in todays' online edition of the journal Angewandte Chemie.

A Molecule Of Many Colors-With rigid wings and a flexible core, a new compound can switch between two shapes and glow one of three colors.

 

Flexible And Fluorescent

A molecule combining rigid anthraceneimide wings and a flexible cyclooctatetraene core switches between a flat and a bent V shape. The R groups are either hydrogens or n-butyl groups.

A Molecule Of Many Colors

Organic Chemistry: With rigid wings and a flexible core, a new compound can switch between two shapes and glow one of three colors.

A new, flexible, multi-ring organic compound fluoresces red, green, or blue depending on its environment (J. Am. Chem. Soc. 2013, DOI: 10.1021/ja404198h). The molecule’s combination of rigid wings and a flexible center could serve as a general design strategy for molecular sensors, the researchers say.

The molecule, developed by a team of researchers, including Shohei Saito, Stephan Irle, and Shigehiro Yamaguchi of Nagoya University in Japan, has two rigid anthraceneimide wings on opposite sides of a floppy cyclooctatetraene core
