The use of structure directing agents (SDAs) in the synthesis of porous
materials is a common practice in materials chemistry. Lately, the interest is
focused on the use of more sustainable approaches upon the use of “greenâ€
solvents and SDAs. Within this context, those approaches based on a certain
economy of reagents are considered even more interesting. For instance,
synthesis carried out in solvents capable to, at a certain stage, play the
role of a SDA and template the structure of the resulting material. Within
this context, we have developed an ice segregation induced self-assembly
(ISISA) process based on unidirectional freezing and subsequent freeze-drying
that is suitable for the preparation of materials exhibiting well-defined
microchannelled structures.1
More recently, we have also explored a second synthetic route that is based on
the use of deep eutectic solvents (DESs). DESs belong to the family of ionic
liquids (ILs) and share most of their characteristic properties (e.g.
nonreactive with water, nonvolatile and biodegradable) and interestingly,
offer certain advantages (e.g. high purity and low cost, among the most
significant). DESs are obtained by complexion of quaternary ammonium salts
with hydrogen-bond donors. In this synthetic approach, DESs can act as a
regular solvent, as a solvent which shows a more or less controlled structure
directing effect or even as a molecular precursor with a well-defined
composition, structure, and reactivity. When all these features are combined
in a single synthesis, the term next generation “all-in-oneâ€
solvent–template–reactant DES-assisted synthesis can be applied.2
In this seminar, we will demonstrate the utility of these approaches for the
synthesis of macroporous and hierarchical carbon materials. The excellent
electrical conductivity of these materials has allowed their successful
application as electrodes in fuel cells3 and supercapacitors,4 and even as
biomaterials after mineralization of the macroporous structure.5

***Francisco del Monte** is a Tenured Scientist at the Instituto de Ciencia
de Materiales de Madrid (ICMM-CSIC), Spain. He received an organic chemistry
BSc degree from the University Autonoma of Madrid (UAM) in 1991, a MSc degree
in polymer science from CSIC in 1992, and a PhD in chemistry also from the UAM
in 1996. He then spent two years as a post-doc at UCLA working on hybrid sol-
gel materials. He has co-authored over 80 scientific papers. At the beginning
of his career, his scientific interest was related to the preparation of
hybrid materials for optical applications. Since 2004, he leads the group of
Bioinspired Materials at the ICMM-CSIC. His current scientific interest is the
use of biomimetic chemistry for the preparation of hierarchically organized
materials.
