WC3.1 - UNIQUE PHOTOPHYSICAL PROPERTIES OF INFRARED ABSORBING POLYMERS
Abstract
Abstract
A nascent challenge for organic semiconductors is their application in infrared optoelectronics. However, infrared absorption is linked to the formation of strong electronic correlations and open-shell character. We use ultrafast spectroscopy to identify and explain the unusual photophysics of these materials.
WC3.2 - ORGANIC SHORTWAVE INFRARED PHOTODETECTORS BASED ON DONOR-ACCEPTOR POLYMERS
Abstract
Abstract
Organic shortwave infrared detectors based on donor-acceptor polymers are advancing rapidly and capable of detectivity exceeding 1011 Jones. This talk will discuss the main bottlenecks associated with charge recombination and trapping. Several integrated system demonstrations will show the various potential applications including spectroscopic identification and image reconstruction.
WC3.3 - DESIGNING ROBUST ORGANIC OPTOELECTRONIC MATERIALS
Abstract
Abstract
In this talk, I will discuss the thin film mechanic of the conjugated polymers aiming to inform the design of robust organic optoelectronic materials. We use flash scan DSC, thin film tensile tester and thin film scattering to aid our understanding of physical property of the optoelectronic materials.WC3.4 - HIGH-SPIN DONOR-ACCEPTOR CONJUGATED POLYMERS
Abstract
Abstract
We discuss new macromolecular design paradigms and strategies to control orbital topology such that very low bandgap donor-acceptor conjugated polymers (DA CPs) can be synthesized in order to yield open-shell species in singlet (S = 0) and triplet (S = 1) spin states.
