Modular Conjugated Polymers for Mid-Infrared Photonic Applications
Polymer Science and Engineering
Over the course of the project related to the development of conjugated polymers for optical to electrical signal transduction of infrared IR light we have made significant strides in many of the originally-proposed research areas. Namely, we have 1 continued to demonstrate the capability to systematically and precisely control the properties of donor-acceptor DA conjugated polymers CPs extending throughout the short-, mid-wavelength infrared MWIR1.4-8 unit vector 14m and long-wavelength infrared LWIR 814 unit vector 14m 2 demonstrated improvements in the capability to control the electronic structure of narrow bandgap conjugated polymers leading to the discovery of new phenomena and functionality from organic materials 3 developed new materials and devices enabling the first examples of photodetection from the SWIR-LWIR using organic materials and 4 demonstrated high performance photoconductive devices that outperform their inorganic counterparts through collaborative efforts with AFRL. Thus, we have been able to advance the design of organic semiconductors OSCs enabling new classes of materials, new optoelectronic and physical functionality, and new device technologies. Moreover, funding of this work by the AFOSR has allowed our team to become a world leader in the chemistry, photophysics, and solid-state device applications of narrow bandgap and open-shell CPs and organic infrared optoelectronics. We have continued to make additional significant discoveries in narrow bandgap materials such as ground state electronics that can be manipulated, conductivities that are higher than other neutral organic solids and demonstrate unique electrical, optical, spin, thermal, magnetic, and quantum phenomena.
