Efficient Conduction of Nonconjugated Small-Molecule Organic Radicals |
초록 |
We present a molecular conductor towards a novel class of electronic material. We investigate electrical properties of a stable radical, h-TEMPO ( 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl), which has well been known for containing stable radicals. The chemical component of this radical molecule allows us to form a single crystal via physical vapor deposition (PVD). The charge transport of this macroscopic open-shell single crystal is rather low, but the thermal annealing of a well-defined single crystal allows the molecule to have a fast charge transfer reaction due to the electronic communication of the open shell site with each other, which results in electrical conductivities greater than 0.05 S m–1. This effort shows a model that differs significantly from the conjugated polymers or molecules generally accepted for the generation of next generation conductors. |
