Dr. Concepció Rovira Angulo receives the award from the Real Sociedad Española de Química of Research Excellence 2015

The Junta de Gobierno of the Real Sociedad Española de Química agreed to approve the Award for Excellence in Research RSEQ 2015 to Dr. Concepció Rovira Angulo in recognition of his outstanding contributions to chemistry, embodied in conceptual developments and studies on multifunctional molecular materials, particularly electronic and / or magnetic properties.

His interdisciplinary research has a substantial effect on the development of nanoscience and molecular nanotechnology. Dr. Concepció Rovira is Research Professor of CSIC, under the Department of Molecular Nanoscience and Organic Materials Institute of Materials Science of Barcelona (ICMAB-CSIC). Recently, he has been awarded the “2013 Distinguished Women in Chemistry” IUPAC Prize.

She is the author of over 300 publications, over 50 in the last five years, with very strong presence in the most important journals in the field of materials and notorious visibility in multidisciplinary chemistry with high impact factor with tens of publications (Journal of the American Chemical Society / Angewandte Chemie / Chemical Science / Nature Chemistry), 8 of them in the last five years. She is the author of numerous patents, including two international and another in operation. In the last five years it has been principal investigator of three European projects and other with state funding; in that five-year period, he has given more than 30 lectures at conferences and national and international centres of research. He has directed 13 doctoral theses, 3 in the last five years.

A pyrene based dyad and triad leading to a reversible chemical and redox optical and magnetic switch

Two new pyrene-polychlorotriphenylmethyl (PTM) dyads and triads have been synthesized and characterized by optical, magnetic and electrochemical methods. The interplay between the different electronic states of the PTM moiety in the dyads and triads and the optical and magnetic properties of the molecules have been studied. The electronic spectra of the radicals show the intramolecular charge-transfer (ICT) transition at around 700 nm due to the acceptor character of the PTM radical. In the diamagnetic protonated derivatives, the fluorescence due to the pyrene is maintained, whereas in the radicals and the corresponding anions there is a clear quenching of the fluorescence. The redox activity of PTM radicals that are easily reduced to the corresponding carbanion has been exploited to fabricate electrochemical switches with optical and magnetic response.
