ChEBI: Terrylene is an ortho- and peri-fused polycyclic arene.
Terrylene in p-terphenyl represents a promising novel single crystalline system for optical spectroscopy of single impurity molecules at low temperatures. The optical spectra of terrylene in p-terphenyl show four origins in absorption and emission, indicating four crystalline sites. In one of the sites, saturated fluorescence count rates of up to 600,000 s?1 were measured for single terrylene molecules[1].
