Potential for exciton condensation in a highly conductive amorphous polymer

An outstanding challenge is to develop molecular materials that exhibit highly efficient energy transfer at ambient conditions. The authors of this study demonstrate the potential of an amorphous material to become an exciton condensate, in which energy can flow with minimal frictional loss. Unlike the Bechgaard salts that support superconductivity only at high pressures, the authors show that the amorphous polymer NiTTFtt, recently synthesized by Xie and Anderson, exhibits the computational signature of exciton condensation at atmospheric pressure and its synthetic geometry. This research supports the realistic possibility of harnessing chemical tunability to achieve ``strongly correlated'' phenomena at more ambient conditions, opening novel avenues for superefficient energy transfer in technologically relevant materials.
