Soon (16th – 20th August 2015) you can find me at the American Chemical Society National Fall Meeting in Boston, USA. Please come and talk to me about all things chemistry, Nature Communications, open access or about our new double-blind peer review option.
Two organic polymers containing alternating electron donating triarylamine and electron accepting thiazolo[5,4-d]thiazole (TzTz) moieties have been synthesized and their redox states investigated. When donor and acceptor units are proximal (polymer 1), electron density is delocalized, leading to a small electrical and optical band gap; these are larger with the inclusion of an adjoining alkynyl-phenyl bridge (polymer 2), where electron density is more localized due to the rotation of the monomer units. As a result, 1 and 2 display different optical and fluorescence properties in their neutral states. Upon chemical and electrochemical redox reactions, radicals form in both 1 and 2, yielding magnetic materials that display temperature independent paramagnetism, attributable to delocalization of radical spins along the polymeric backbones. The ability to convert between diamagnetic and paramagnetic states upon chemical oxidation and/or reduction allows for the materials to display switchable magnetism and fluorescence, imparting multifunctionality to these solid-state purely organic materials.
As of January 2015, I have taken up a position based in the London office of Nature Publishing Group. I will be working as an assistant editor at Nature Communications.
Nature Communications is an open access journal that publishes high-quality research from all areas of the natural sciences and has an Impact Factor of 10.742 according to the 2013 Journal Citation Reports® Science Edition (Thomson Reuters, 2014). Papers published by the journal represent important advances of significance to specialists within each field.
