Dr. Agustí Lledó

Agustí Lledó (1980, Barcelona) obtained is PhD in Chemistry from the University of Barcelona (UB) in 2006 under the direction of Prof. Antoni Riera. In 2007 he moved to The Scripps Research Institute (TSRI) to pursue post-doctoral studies with Prof. Julius Rebek Jr. In 2010 he returned to his home town and joined the Institute for Research in Biomedicine, Barcelona (IRB Barcelona) as a “Juan de la Cierva” research fellow. In 2014 he moved to University of Girona as a “Ramon y Cajal” (RyC) researcher. His research interests include organic supramolecular chemistry, catalysis an organometallic chemistry. Dr. Lledó leads two ongoing projects at IQCC, one in the area of biomimetic supramolecular catalysis (financed through the RyC program), and another devoted to the bottom up synthesis of carbon nanostructures (financed through “Explora Ciencia” project CTQ2014-61629-EXP). Dr. Lledó also forms part of the DiMoCat group and actively participates of various research projects in the area of transition metal catalyzed reactions.

Research overview

Our research program focuses on two different topics with catalysis as a central leitmotiv. The first research line is directed to the development of biomimetic supramolecular catalysis, i.e., the realization of complex organic transformations catalyzed by artificial receptors mimicking the mode of action of natural enzymes. The second topic seeks to exploit photocatalysis as a new approach towards the bottom up synthesis of carbon nanostructures.

Biomimetic Supramolecular Catalysis

Chemists have long sought to emulate the efficient way in which organic compounds are made in nature, with limited success. One of the distinct features of enzymatic catalysis is the confinement of the substrate in the hydrophobic cavity of the active site. This has multiple consequences for the reaction outcome, including reaction acceleration, modification of the selectivity and suppression of detrimental side reactions thanks to isolation of the substrate from the bulk medium. We seek to emulate this behavior employing cavitands (picture), artificial receptors with a ?-rich hydrophobic pocket and a fluxional behavior akin to those of enzymes. We pursue the preparation of new cavitand receptors with improved binding profiles and functionalities, in order to carry out complex carboacationic cascade reactions in a straightforward manner.


Carbon Nanostructures

Carbon based nanomaterials promise an exciting technological revolution in the field of materials science, but their mass production still faces important challenges. Single-walled carbon nanotubes (SWNTs), for instance, display distinct and unique electrical properties –which make them desirable for electronic and photovoltaic applications–, but only when obtained uniformly in well-defined dimensions. Graphene and graphene nanoflakes can offer even more astounding properties but bottom up approaches for their preparation are still at its infancy. This research line aims at the preparation of carbon nanostructures using batch processing in solution, exploiting photocatalysis and employing readlily available carbon feedstocks such as olefins or aldehydes.
