Assemblies for Solar FuelsAbstractThe dye-sensitized
photoelectrochemical cell (DSPEC) represents a novel approach to
combining molecular chromophores and catalysts with semiconductors to
effect light driven production of solar fuels. A multidisciplinary
approach has been used to develop and study molecular and polymer
assemblies for light driven water oxidation at a DSPEC photoanode and
proton reduction at a photocathode. The work aims to understand
mechanisms and dynamics for the photoprocesses occurring at the
molecular/semiconductor interfaces. The talk will present an overview of
work done during the past several years, involving the design,
construction and study of molecular and polymer-based assemblies of
light absorbing chromophores and catalysts, primarily aimed at water
oxidation at the DSPEC anode. References:一.Leem, G. et al. Light-Driven

polymers have been the cornerstone of organic electronics, with
applications in areas such as photovoltaics, 田野(field) effect transistors,
and electrochromics. Specifically, polymer based solar cells have
generated significant attention due to the promise of a lightweight,
flexible, and inexpensive solar energy conversion platform. However, a
number of challenges are still apparent, including scalability and
efficiency. Our related efforts have focused on novel, simplified
polymer and device architectures and synthetic methods. Specifically,
our work on ternary blend solar cells will be discussed, focusing on how
proper selection of components in ternary blends can lead to a
synergistic enhancement of properties without increasing the complexity
of device fabrication. Here our development of the organic alloy model
will be discussed in relation to the influence of polymer blending on
the open circuit voltage in ternary blend solar cells. Additionally, we
have spent significant effort focusing on scalability of polymer
synthesis, which is best embodied in our work on Direct Arylation
Polymerization (DArP), which is a C-H activation route to the synthesis
of conjugated polymers. In this case, the identification of defects and
their elimination via optimization of polymerization conditions has been
the central focus of our work. Efforts toward oxidative direct arylation
or halogen-free polymerization will also be discussed along with
preliminary results in continuous flow chemistry.个人简单介绍:Barry C.

摘要:

2018年4月18日

Conjugated polyelectrolytes feature p-conjugated backbones that are
functionalized with polar, ionic side chains. These polymers have very
strong optical absorptivity due to the conjugated electronic system, and
the HOMO-LUMO gap can be controlled by tuning the electronic nature of
the monomer units. CPEs are polymer amphiphiles, and consequently they
self-assemble in solution into colloidal aggregates, and they can be
deposited onto surfaces to afford nanostructured films by using the
layer-by-layer method. Due to the p-conjugated backbone, CPEs exhibit
photonic properties, exhibiting strong absorption in the visible region
and strong fluorescence. Fundamental studies of the self-assembly of
CPEs in solution and at interfaces, along with their application as
biosensors and in hybrid solar cells will be discussed.

报告摘录:

Kirk S. Schanze教师简历

Conjugated polyelectrolytes(CPEs) featuring poly(phenylene ethynylene)
and poly(thiophene) backbones substituted with ionic solubilizing groups
are water soluble. These materials display a variety of interesting
properties, including self-assembly into nanoscale aggregates, ability
to process into layer-by-layer films and optical/stimuli responsive
behaviour in the presence of ions, surfactants and biomacromolecules. We
have explored the use of cationic CPEs as fluorescent sensors for
polyphosphates(pyrophosphate, ATP and ADP). In addition, cationic CPEs
exhibit strong light-activated biocidal activity vs. a broad spectrum of
bioagents, including bacteria, virus particles and spores. The talk will
overview recent work in this area, including the interaction with
cationic CPEs with mammalian cells.
