ver the last decade, the generation of organic porous (nano) materials with tunable pore sizes and desired

functionalities has been the subject of increasing attention in materials science. Interest in such porous

frameworks originates from the large variety of applications in which they are involved, e.g. size/shape-se-

lective nanoreactors, monoliths for advanced chromatographic techniques, nanofiltration membranes, high

specific area catalytic supports, as well as 3-D scaffolds for tissue engineering. Porous monolithic polymers may

represent suitable supports for the immobilization of metallic nanoparticles, thus allowing for the generation

of hybrid materials having particularly interesting features for heterogeneous supported catalysis. Such porous

materials indeed present some undeniable advantages over their inorganic counterparts, namely their syn-

thesis is cost-effective and their mechanical properties as well as the chemical nature of the pore interface can

be finely tuned. In this context, we have developed different polymer-based hybrid systems based on porous

polymers that were suitably functionalized so as to successively immobilize gold nanoparticles. This presen-

tation will particularly emphasize on recent studies developed in our laboratory on this topic. It will focus on

hybrid systems based on three main types of porous polymers: Nanoporous polystyrene frameworks arising

from polystyrene-block-poly(D,L-lactide) diblock copolymers with a cleavable functional group at the junction

between both blocks; bulky macroporous monoliths prepared from a selectively cleavable disulfide dimeth-

acrylate monomer; functionalized doubly porous poly(2-hydroxyethyl methacrylate)-based networks. Such

functional hybrid materials have been successfully applied as efficient and versatile heterogeneous supported

catalysts in miscellaneous model organic reactions, including hydride-mediated reduction of nitroaromatic

compounds, C-C homocoupling of benezeneboronic acid derivatives and reduction of dyes. We have notably

demonstrated that cascade reaction processes consisting of two successive nanogold-catalyzed reactions are

efficiently implemented with these novel porous polymer-supported catalysts.

Daniel Grande is currently working as a CNRS Research Director at the East-Paris Institute of Chemistry and Materials Science (IC-

MPE) in France. He received his PhD degree in Polymer Chemistry from the University of Bordeaux, France and the University of

Coahuila, Mexico in 1998 and then he spent about two years at Emory University, USA as a NIH post-doctoral fellow. His research

interests include the development of functional polymer materials with a broad range of porosity scales and the whole spectrum

from their design to their potential applications is investigated. He is the co-author of about 110 peer-reviewed publications in

international journals, 40 proceedings, 14 book chapters and 11 patents.
