O
rganic semiconductors with tunable optoelectronic
properties represent a versatile class of multifunctional
materials that can find usages in flexible electronics and
energy-relatedapplications. Some fundamental aspects related
to their optoelectronic properties are the control of molecular
packing, long range ordering, as well as donor-acceptor
interfaces, all of which are essential for charge separation and
charge transport. Our approaches toward high performance
semiconductor materials include (a) developing electroactive
building blocks that satisfy bandgap engineering, high
absorptivity, and (b) utilizing strong intermolecular interactions
to tune chain packing and facilitate charge transport. In this
presentation, our recent advances on the development of new
electron donors, acceptors and a novel quinoidal unit and their
incorporation in conjugated polymers will be discussed. The
combination of molecular level understanding of material
composition and control of thin film ordering, offer great
opportunity for the development of novel high performance
electronic materials.
Biography
Yi Liu is a career Staff Scientist at the Molecular Foundry, Lawrence Berkeley
National Laboratory, USA. He obtained his PhD in Chemistry in 2004 from
the University of California, Los Angeles, under the direction of Sir J Fraser
Stoddart. After finishing his Post-doctoral Research with Professor K Barry
Sharpless at the Scripps Research Institute, he joined theMolecular Foundry
in 2006 as an Independent Principal Investigator. He is currently the Director
of the Organic and Macromolecular Synthesis Facility. His research inter-
ests are design and self-assembly of functional organic and organic-inor-
ganic hybrid framework materials, materials chemistry for organic electron-
ics, and fundamental understanding of the associated electronic processes.
