Uses
Perylene has been used as an acceptor for pristine C70 to be used as a sensitizer for efficient triplet-triplet annihilation upconversion; which has shown improved stability under continuous laser irradiation compared to the benchmark Pt(II)-ocetaethylprphyrin. Perylene has also been used as a dopant representing blue fluorescent dye on a white-emitting polymer film. Dyes and metabolites.
Definition
ChEBI: An ortho- and peri-fused polycyclic arene comprising of five benzene rings that is anthracene in which the d,e and k,l sides are fused to benzene rings.
General Description
Perylene molecules are fluorescent in nature. Ultraviolet photoemission spectroscopy and low energy electron diffraction of the structure of 4? thick perylene dye layers adsorbed on the surface of Ru (0001) has been investigated.
Safety Profile
Questionable carcinogen. Mutation data reported. Whenheated to decomposition it emits acrid smoke and irritating fumes.
Purification Methods
Purify perylene by silica-gel chromatography of its recrystallised picrate. [Ware J Am Chem Soc 83 4374 1961.] Crystallise it from *benzene, toluene or EtOH and sublime it at 142o in a flow of oxygen-free nitrogen. It forms a 1:1 *benzene-complex (m 223-224.5o needles from *C6H6), and a 1:2 *benzene-complex (m 154-155o from *C6H6 or H2O). The 2,4,7-trinitrofluoren-9-one has m 270-271o (from EtOH/*C6H6).
