1. Perylene was also synthesised from 1, 1-binaphthalene in 1913.2. Although structurally a derivative of perylene , it is produced from acenaphthene. 3. Perylene can be also used as an organic photoconductor.4. Perylene derivatives display high electron affinity and chemical stability.5. In 1910 Scholl reported the synthesis of a quinone and of perylene from naphthalene both with aluminum chloride. 6. Due to their specific pi-electron distributions, hydrocarbons such as perylene and triphenylene are not considered radialenes. 7. DIP is a planar perylene derivative with two indeno-groups attached to opposite sides of the perylene core. 8. DIP is a planar perylene derivative with two indeno-groups attached to opposite sides of the perylene core. 9. In particular, high conductivity of 0.12 S / cm was reported in perylene -iodine complex in 1954. 10. J-aggregate dyes are found with polymethine dyes in general, with cyanines, merocyanines, squaraine and perylene bisimides.
