Sulfur-rich polyaromatic architectures:
asterisks, dendrimers, polymers, and their
metal interactions
S ulfur-rich polyaromatic architectures of various
topologies will be presented, along with their
synthesis, their opto-electronic properties and some
applications in chemical-biology, in materials science
and in nanoscience. They comprise asterisks,
dendrimers, polymers and helicenes, which often
incorporate a thiophenylene or a polyaromatic unit,
leading to some molecular rigidity and restricted
degrees of freedom. They represent an underexploited
class of macromolecules with multivalent and attractive
features for exalting supramolecular interactions,
chiroptical and electronic properties. The latter features
could be modulated from the coordination of divalent
sulfur atoms to thiophilic metallic species, from some
cation-π interactions, and from some π-π complexes.
Additionally, polysulfuration often enhances some
electronic, photophysical and biophysical properties,
leading to exalted luminescence, stable redox
states, metal-ion coordination ability, aggregation
or crystallization-induced phosphorescence or
fluorescence emission (AIE or CIE). Some uses will be
presented as asymmetric catalysts, as some of the most
phosphorescent organic (nano)crystals (π~100%), as
cation-selective membranes, as cations/anions sensors
(dual mode), as electrochromic molecular switches, as
multivalent glycosylated biosensors, and as ligands
for stabilizing metal alloys and bimetallic core-shell
nanoparticles.
Biography
Marc Gingras chemistry at the University of Sherbrooke (1981-84). From 1985-89,
he completed Doctorate at McGill University with Professor T H Chan and David
N Harpp. He worked with Professor Edwin Vedejs (1989-92) and with Professor
Laura Kiessling (1992-93) at the University of Wisconsin Madison. He then joined
the Laboratory of Supramolecular Chemistry at the University of Strasbourg with
Professor Jean Marie Lehn (1993-95). He occupied several faculty positions:
Université Libre de Bruxelles (1995-99), University of Nice (1999-2007), and Aix-
Marseille Université at the Interdisciplinary Center on Nanoscience of Marseille.
He was Chairman of the Chemistry Department (2010-11). He guided 80 research
trainées. He has a list of more 62 publications (~2000 cit.), 115 invited lectures
and 30 short ones. He is a Board Member of Austin Journal of Biosensors and
Bioelectronics, and a former one of the Journal of Sulfur Chemistry (2010-14) and
ISRN Organic Chemistry (2010-12).
