Titre: Les polymères structurellement dynamiques en tant que matériaux
sensibles aux stimuli
Title: Structurally Dynamic Polymers as Stimuli-Responsive Materials
Résumé/Abstract:
Dr. Stuart J. Rowan
Mettalo-Polymers
Biomaterials
The dynamic bond can be defined as any class of bond that selectively undergoes reversible breaking and reformation, usually under equilibrium conditions. The incorporation of dynamic bonds (which can be either covalent or non
-covalent) allows access to structurally dynamic polymers.1 Such polymers can
exhibit macroscopic responses upon exposure to an environmental stimulus, on
account of a rearrangement of the polymeric architecture. In such systems the
nature of the dynamic bond not only dictates which stimulus the material will
be responsive to but also plays a role in the response itself. Thus such a design
concept represents a molecular level approach to the development of new stimuli-responsive materials. We have been interested in the potential of such systems to access new material platforms and have developed a range of new mechanically stable, supramolecular structurally dynamic polymer films that
change their properties in response to a given stimulus, such as temperature,
light or specific chemicals. Such supramolecular materials have been targeted
toward applications that include healable plastics,2,3,4 responsive liquid crystalline polymers,5 chemical sensors,6 thermally responsive hydrogels,7 shape
memory materials8 and mechanically dynamic biomedical implants.9,10 In this
presentation we will focus on two classes of stimuli-responsive materials (1)
photo-healable/shape-memory materials and (2) mechanically dynamic cortical
implants.

Titre: La couleur dans les polymères conjugués : électrochromisme et photovoltaïque
Title: Color in Conjugated Polymers: Electrochromism and Photovoltaics
Dr. John R. Reynolds
Résumé/Abstract:
Conjugated molecules, oligomers and polymers with intimately interacting
donor-acceptor moieties provide light harvesting and electronic energy levels that can be tuned to optimize their utility in electrochromic, along with
both bulk heterojunction and dye sensitized solar cell applications. In this
presentation, we will explore the combination and interaction of a breadth
of electron rich and electron poor species that ultimately allow us to prepare
polymer films with band gaps that range from 4 eV in the UV to near 0.5 eV
in the infrared. The flexible synthetic chemistry of dioxythiophene-based
polymers has allowed us to complete the color palette (yellow, orange, red,
purple/magenta/, blue, cyan, green, and black) of vibrantly colored to highly
transmissive switching, spray- and blade-coat processed electrochromes of
any color, with donor-acceptor interactions especially enabling materials
that are black, green and cyan in color. Donor-Acceptor-Donor (DAD) triads
with internally fused DA cores provide a means of examining multi-colored
chromophores for charge injection to metal oxide electrodes. DA polymers
synthesized using a broad selection of co-monomers, provides donor polymers, which, in conjunction with PCBM, yield solar cells with power conversion efficiencies of 7-8%, while providing color control. Combination of
multi-layer solution processing allows the construction of solar powered
electrochromic windows.
